                            SETTING UP
                            ----------

WARNING: Don't forget to turn  off the  power to  your Spectrum
before  you connect or disconnect any peripherals, including the
PLUS D.

With the power  off,  carefully  connect  your  PLUS  D  to  the
computer and your disc drive and printer to the PLUS D, as shown
in the diagram above.   If  you  are  using  other  peripherals,
connect them to the computer in their normal places.  If you are
using   a  peripheral  which  plugs  into  the  Spectrum's  edge
connector,  you'll need to use a "Y" connector so that it can be
attached at the same time as the PLUS D.

For the first steps, you'll  need to have your cassette recorder
connected to the computer in the normal way.

Turn  the Spectrum power on and the normal Spectrum introductory
screen  will appear on your monitor/TV.  The red indicator light
on  your PLUS  D will  come on,  indicating that  the electrical
connection  between  the  PLUS  D  and  the  Spectrum  has  been
correctly  made.  Turn on the power to the disc drive and insert
a blank disc.

If you are using the Spectrum 128K or + 2, go into the EDIT mode
and then  move the cursor  to select SCREEN.   Then press ENTER.
You must be in this screen mode to avoid problems later.

Problems?
---------
    The  indicator light  on your  disc drive  stays on  all the
time with the PLUS D attached.
    Don't  worry -  it's normal.  We  keep the light  on to show
which was the  last drive in  use.  Later you'll  see how useful
this is.























                            page 3

                    CREATING YOUR SYSTEM DISC
                    -------------------------

You'll  have noticed that a cassette  has been supplied with the
PLUS D.  The program on the System Cassette asks you a series of
questions about your  system - what  sort of disc  drive are you
using? are you using a printer?  etc.   You  need  to  load  the
program from cassette in the normal way.

Make sure  you have  a blank  disc in  your drive.   Don't worry
about  formatting the disc - that comes later.  (And don't worry
if you  don't understand  what formatting  is, either:  all will
soon be clear!)  Make sure that the drive is turned on.

Then simply  follow the instructions on  screen.  Don't worry if
you make  a mistake  while answering  the questions.   You'll be
given the opportunity to repeat  everything at the end.

By answering  the questions,  you create  your own  SYSTEM FILE.
The final instructions in the  program  allow  the  file  to  be
transferred  to disc.  Once this has been done, you have created
a SYSTEM  DISC, and  if you  follow our  instructions carefully,
you'll probably  never need the System  Cassette again.  (But we
recommend that you  keep the  cassette stored  in a  safe place,
just in case!  Why not store it in the PLUS D's original carton,
which  you should keep  just in case  you ever need  to send the
unit back for repair?)


Problems with SYSTEM FILE questions?
                                     
1.  I  keep getting an error message  "Nonsense in Basic" at the
end of the section on disc parameters.  What's going wrong?
    The problem is probably that a clean connection is not being
made  between the  PLUS D  and the  computer.  Try  cleaning the
computer's  edge connector.  It this doesn't work, try to borrow
a friend's computer  and see whether  the PLUS D  will work with
it,  If this  is successful it's  likely that you  have a faulty
line on your computer  (which  may  not  necessarily  have  been
apparent  with other interfaces).  But if it still doesn't work,
then you probably have a faulty PLUS D - return it.

2.  I don't know the stepping rate of my disc drive.
    The vast majority  of drives work  on a 6  or 12 millisecond
stepping rate.   If your drive seems  to be behaving erratically
later, try slowing  the stepping  rate.  Some  3" drives  have a
stepping rate of 30 milliseconds.

3.  I don't understand the control codes in my printer manual.
    Yes, printer manuals are notoriously difficult.  But if you
are stuck, contact INDUG  -  the  users'  group.   Full  contact
details are in the Introductory issue of FORMAT.

                        USING A DISC DRIVE
                        ------------------


Compatible Disc Drives

The PLUS D will work with  any  drive  which  has  the  industry
standard Shugart 400 connection interface (ask your dealer for a
"Shugart 400-type") and  which  is  capable  of  double  density
operation.  This means most drives  which  work  with   the  BBC
range of computers (but not single density drives, and if you're
buying a drive, make  sure that  it has  its own  power supply).
You can use  one or two  drives; To get  maximum efficiency from
the PLUS D, we recommend 3.5" or 5.25" 80-track double sided and
double density drives, which will give you up to 780K of storage
per drive.  But Shugart 400-type 3" drives will also work.  Make
sure you  also  buy  good-quality  discs  which  have  the  same
specifications as your drive.

If you want to  use two  drives, you  can buy  them in  a single
"dual" case  with a single  power supply and  connector.  Or you
can  use two single drives in tandem, attaching them to the PLUS
D via a double drive connector.



Loading the Disc Operating System


Connect  the computer, the PLUS D and the disc drive(s) and turn
on the power.  The normal Spectrum title screen will appear, and
the indicator lights on the PLUS D and on disc drive 1 will come
on.

Insert  your System Disc in disc drive 1.  Type RUN, then ENTER.
The disc drive will  go into  action for  about two  seconds and
while  this  is  happening, the  PLUS  D  indicator  light  will
temporarily go out  (- the light  always goes out  while you are
actually using the drive).   When  the  System  is  loaded,  the
screen will display;

    Miles Gordon Technology G+DOS1

and an OK message:

    O.K. G+DOS1. 0:1

(G+DOS stands   for  the  Gordon Disc  Operating System  for the
PLUS D.  The 1  which follows  shows the  version number  of the
DOS, and this may change from time to time.)









                            page 5

The Catalogue

Type CAT 1 (or CAT 2 if you wish to access drive 2) - ENTER.

In about two seconds the screen will display:
    - The heading PLUS D Disc 1 (or 2) Catalogue.
    - A list of the files on the disc with various comments.
      (The maximum number of files per disc is 80.)
    - The amount of free space on the disc in kilobytes.

A typical catalogue screen looks like this:
    1   +SYSTEM     14      CDE          8192,5656
    2   CONFIG      31      BAS          9100
    3   CONFIG1_C    4      CDE         40300,1750
    4   CONFIG2_C   14      CDE         42240,6656
    5   CONFIG3_C    1      CDE         49000,60
    6   snap F      97      SNP 48K
    7   screen      14      SCREEN$
    8   listing     34      M/DRIVE
    9   data         8      SPECIAL
   10   numeric      4      D.ARRAY
   11   character    5      $.ARRAY

    Number of free K-bytes  =  667

Most  of  the  information   on   this   catalogue   screen   is
automatically  displayed by  the PLUS  D.  The  only information
which you have to supply is the file-name, which is shown in the
second column.   These file-names  can be  up to  ten characters
long, in upper case or lower case characters, or both.

The first column on the left shows the program number.  Whenever
you  save a file,  the PLUS D  will give it  the first available
program  number.  So,  if you  have the  catalogue shown  in the
example  above, the next file you save will automatically become
program number 12.  This program number will stay the same until
the file is erased (we do not list files in alphabetical order).
But if you erased, say, program number 8, then the next file you
save  to the disc will become the  new program number 8 - taking
the first available program number.

The third  column shows the  number of disc  sectors used.  Each
sector holds  512 bytes  (= 1/2  kilobyte), so  to find  out the
number of kilobytes used for each file, divide the number in the
third column by 2.

The fourth column  is for  the type  of file,  which the  PLUS D
automatically  selects.  The  different types  are shown  in the
table at the top of page 7.  You probably won't fully understand
the  significance of all these different  types of file yet, but
most of  them are  covered in  this Introductory  Manual.  Those
marked   with  an  asterisk  are  likely  to  be  used  by  more
experienced programmers  and demand  fuller explanation  than we
can  give in this Manual: but  FORMAT - the newsletter published
by the  Users Group, INDUG - explores  them in detail in regular
articles.



                            page 6

    BAS                 =   Basic
    CDE                 =   Code
    SNP 48K             =   48K Snapshot File
    SNP128K             =   128K Snapshot File
    SCREEN$             =   Screen File
    M/DRIVE             =   Microdrive File                     *
    SPECIAL             =   Special File                        *
    D.ARRAY             =   Data Array
    $.ARRAY             =   Character Array
    OPENTYP             =   File created by OPEN # statement    *
    EXECUTE             =   Execute File                        *

                        PLUS D File-Types

The  right-hand column in  the catalogue tells  you the starting
address of  the file, and, after the  comma, the number of bytes
used if it is a code file.  If it is a file in Basic, the number
will show the line at which the program starts.

The amount of free space  left  on  the  disc  is  displayed  in
kilobytes at the bottom of the screen.

Remember   that  the  PLUS  D   displays  all  this  information
automatically.  All you'll  have to do  is to select  a name for
each file - and we'll explain how to do this later.

If  your catalogue fills the screen, and you wish to scroll down
to the next screen, press ENTER.

You  can also display an abbreviated  catalogue by typing CAT 1!
(or CAT 2!).  This would show the same catalogue in this format:

    +SYSTEM     CONFIG      CONFIG1_C   CONFIG2_C
    CONFIG3_C   snap F      screen      listing
    data        numeric     character

Both the full  and the  abbreviated catalogue  can be  listed on
screen simultaneously.   Or you could, for  example, list disc 1
in  full and disc 2  in the abbreviated form  (but you must list
the  full catalogue first, as CAT 1 clears the screen, while CAT
1! does not)

If  you wish to print out the catalogue on your printer, you can
use the special CAT  #3  command.   For  example,  to  send  the
catalogue on drive 1 to the printer, you enter:
    CAT #3;1
To print an abbreviated catalogue from drive 2, you enter:
    CAT #3;2!

Question
--------
    What are the files that are  already on my disc - +SYSTEM,
CONFIG, CONFIG1_C, CONFIG2_C, and CONFIG3_C?
    +SYSTEM is the system file that you created earlier.  The
other four  files allow you  to re-load the  set-up program from
disc  if you wish to change your system file later.  If you ever
need to do this, simply load in the CONFIG program.


                            page 7

PLUS D Disc Drive Commands

When  you use the PLUS D and  a disc drive, Basic commands typed
on the  computer keyboard are followed by  a Syntax Operator - a
code to let the computer know that the instructions are directed
toward the disc drive, and not, for example, to a tape recorder.

For ease of explanation in this Manual, the syntax operator will
always be referred to as Dl, meaning that the instruction is for
drive  number 1.  However, when you are working on the computer,
the following options are also available:

    Dl or dl  =  a command for drive 1
    D2 or d2  =  a command for drive 2
    D* or d*  =  a command for the last drive in use

(Programmers  should note  that D*  is particularly  useful when
your disc file  autoruns and calls  up another file  on the same
drive.   Also note  that a  variable can  be assigned  for drive
number 1 or 2 but not for *.)

By typing an upper case D rather than a lower case d when saving
a  file,  the  abbreviated  disc  catalogue  will  be  displayed
automatically when  the save is complete.   A new catalogue also
appears  automatically if you type an  upper case D when erasing
or renaming a file.

Alternatively,  the   PLUS  D  also   understands  the  Sinclair
Microdrive syntax.  For example, you can load a file by entering
        LOAD *"m";1;"file-name"
The PLUS D  syntax will  obviously be  preferred by  most users,
since it is  much easier  than Microdrive  syntax.  In  fact, we
only  mention that the  PLUS D understands  Microdrive syntax in
order to make the point  that  most  programs  written  for  the
Microdrive will  be able to  run without alteration  on the PLUS
D's disc system.   One  small  change  may  be  required:  if  a
Microdrive program  uses a CLOSE  # statement, you  will have to
modify this  to CLOSE #*.  We  are obliged to use  the * to fail
syntax in order to correct a small bug in the Spectrum.


Saving a File and Verifying

First,  ENTER this  short program  called "Squares".   We'll use
this program to show the PLUS D's various disc operations:
    10  REM   Squares
    20  FOR   n=1 TO 10
    30  PRINT n,n*n
    40  NEXT  n

Then, to save the program on the disc in drive 1, ENTER:
    SAVE   Dl "Squares"

The  screen border will flash (provided  that you said it should
when you were  setting up your  System File), and  after about 2
seconds the program will be saved.



                            page 8

As described  in the  last section,  if you  have saved  using a
capital D,  the  abbreviated  disc  catalogue  is  automatically
displayed.    You'll  see  the  program  Squares  shown  on  the
catalogue as the  last entry.   But if  you wish,  you can  do a
further check to ensure that  the  program  has  been  correctly
saved, by entering:
    VERIFY Dl "Squares"
When  the O.K. message confirms the save, clear Squares from the
computer's memory by entering NEW.


Loading a Program

Now you can reload Squares from the disc, by entering
    LOAD Dl "Squares"

When the O.K. message appears, the program has been loaded,  But
so  far we haven't given an instruction to make the program run.
Let's do that now by entering:
    SAVE Dl "Squares" LINE 10

But of course, there's already a program called Squares saved on
the  disc.  The PLUS D  tells you this and  asks you whether you
wish  to overwrite the existing file by  entering Y (= Yes) or N
(= No)   Enter Y.  Then:
    LOAD Dl "Squares"


Breaking into a Program

To  break into  the program  and stop  Squares running,  use the
normal Spectrum BREAK key.

Note that BREAK  will  stop  the  computer  running  all  normal
routines, but  it will have  no effect during  a disc read/write
(i.e.  Load or Save) operation until  the disc activity has been
completed.


Renaming a File

To  rename a file,  we use the  two keywords ERASE  and TO.  For
example, let's rename the Squares file as Example 1:
    ERASE Dl "Squares" TO "Example 1"
The  abbreviated catalogue will confirm that the change has been
made.

The  file-names you choose can be any combination of letters and
numbers  - or even spaces - but the maximum number of characters
is ten.   You can  use upper-case  or lower-case  characters, or
both.  In  the catalogue, the file-names  will appear exactly as
you originally typed them,  but  when  you  re-load  a  file  it
doesn't matter  if letters  originally typed  in lower  case are
changed to upper case, or vice versa.

Warning:  Don't use the characters ? or * in your file-names, as
this may cause problems with other commands we deal with later.


                            page 9

Copying a File

To copy a  file, use  the two  keywords SAVE  and TO.   Copy the
program you have written by entering:
    SAVE Dl "Example 1" TO  Dl "Newcopy"
You'll see that before the copy  is  made,  you  are  given  the
opportunity to change the disc.  If you don't need to change the
disc,  press the SPACE  bar and the  file will be  copied on the
same disc with the new file-name.

Perhaps  you wish to  back up the  file on a  different disc but
with  the same file-name.   (ALWAYS do this  with your important
files.)  In this case, using your original disc, you enter:
    SAVE Dl "Example 1" TO Dl
Once  again you  are given  the opportunity  to change  the disc
before  you press the SPACE bar to make the copy - and of course
you'll do so  if You're making  a back-up on  another disc.  But
if  you don't change the disc and press the SPACE bar, you'll be
told that the  File-name exists  and asked  whether you  wish to
overwrite the existing file.  Press Y (= Yes) to overwrite, N to
cancel the command.

If you  are using two disc drives with  the PLUS D, you can also
copy a file from one drive to the other, using the command:
    SAVE Dl "File-name" TO D2
If  you add a file-name after D2, the new copy will have this as
its new  file-name: otherwise, the  new copy will  have the same
name as the original,

(Note that the SAVE...TO command will not copy two types of file
which  we come to later - Snapshot files and files created by an
OPEN # statement.

When  copying is complete, the Spectrum automatically receives a
NEW instruction  and your  screen will  be cleared.   Check that
your copy has been  made, and  find out  how the  full catalogue
looks now by entering CAT 1.  If you've followed the suggestions
here,  your catalogue should include a file called Example 1 and
another  called Newcopy.  Note the amount  of free space left on
your disc.


Erasing a File

Let's now erase the file called Example 1, by entering:
    ERASE Dl "Example 1"
After the erase,  your abbreviated  catalogue will  confirm that
Example 1 is no longer there.  Enter CAT 1 for the full listing,
and  you'll see that more  space has been made  free on the disc
(although this  is such a small program  that any change will be
minimal!)

(Note that unlike Interface 1,  the  PLUS  D  returns  an  error
message if you  try to  erase a  non-existent file.   When using
programs originally  written for  Microdrive, you  may sometimes
need  to delete ERASE commands in the listing to avoid the error
message when the program is running.)

Creating an Autoload File

An  autoload file  is one  which loads  as soon  as you  RUN the
operating system; you are allowed one autoload file per disc.

For  an illustration of an autoload  file, let's rename the file
Newcopy.  Enter:
    ERASE Dl "Newcopy" TO "Autoload"

When  the catalogue confirms that the change has been made, turn
off the power  to your Spectrum  so that you  lose everything in
the  computer's memory.   (Turn off  the power  - don't  use the
Spectrum's reset button - we're  coming  to  this  in  the  next
section.)

Turn  on the power again and load the operating system from your
system disc by entering  RUN.   Your  Autoload  program  (which,
you'll remember, is the original Squares program) will be loaded
at the same time, and instead of the normal PLUS D title screen,
you'll see the Squares program running.



The Spectrum's Reset Button

All  Spectrums from the ZX Spectrum + model onwards have a reset
button  which allows you to reset  your system without having to
turn off the mains power.

When  you have  the PLUS  D attached,  and press  the computer's
reset  button, everything stored  in the Spectrum's  RAM will be
lost as usual, but the PLUS D still retains the operating system
in its own memory - unless the DOS has been corrupted or changed
in some  way, and  this is  automatically detected.   This means
that you don't need to reload  the  PLUS  D's  system  from  the
system disc - you just carry on giving normal PLUS D commands.

Of  course, if power  to the computer  is turned off,  or if the
system  has been corrupted, the PLUS  D's operating system is no
longer retained  in memory.  To be able  to use PLUS D commands,
you'll  then have to load the  operating system from your system
disc (or technically, "boot up") afresh.



Problems?
---------
    Every time I enter a PLUS D command, nothing happens except
a question  mark that appears in the  command line on the screen
when I press ENTER.
    You haven't  loaded the  operating  system  -  the  Spectrum
doesn't  recognise the Dl  syntax operator unless  the G+DOS has
been booted up.  Did you forget to load the system in?  Have you
tried using a different system disc in case the one you're using
now has been corrupted.




                            page 11

Snapshot Files

For many  PLUS D users, one of  the most important features will
be  the interface's ability  to transfer virtually  any piece of
Spectrum  software to disc easily and  instantly by means of the
Snapshot Button.  You can take Snapshot saves at any time during
a  program and as often as you  like; if you are a games-player,
you'll find it especially valuable to be able to:
- start a game at an advanced level instead of at the beginning
- come  back to a game on another occasion and start at exactly
the point where you had to leave it last time
- keep a permanent record of your high scores.

A Snapshot save  is made when  you press the  Snapshot Button on
the   PLUS  D  once.   Anything  and  everything   held  in  the
Spectrum's memory at that  time is  saved to  the last  drive in
use, shown by the indicator light on the disc drive.

But there are  three  different  types  of  Snapshot  file.   To
experiment, first make sure that your system has been booted up.
Then load  in any program (a game  is best for demonstration) in
the normal way - from disc or from cassette.  (If you're loading
from  cassette, you should  of course use  the Spectrum's normal
LOAD "" command, and not the special PLUS D disc syntax.)

When the program has  loaded  and  started  to  run,  press  the
Snapshot  Button. You'll notice that your program will be frozen
at  its   current  status,  and   you  will  see   a  number  of
multi-coloured lines filling the borders on the screen.  You now
have three Snapshot save options:

Press  key 3 on the Spectrum to save only the current SCREEN.  A
screen  save will occupy 7K of memory space on a disc.  When the
save  is complete, you'll see that  the program will continue at
the same point from which you left it.

Press key  4 on the  Spectrum for a  48K PROGRAM to  be saved to
disc.  Every time  you save a  48K program, 48K  of memory space
(or actually 97 sectors)  will be  used on  the disc.   When the
save is complete, in just  over  3  seconds,  the  program  will
continue  from the point at which you  left it.  If you want to,
you can take more Snapshots at later points in the program until
your disc is full - that's up to 16 Snapshots per disc on a 780K
capacity drive.

Press key  5 on the Spectrum  for a 128K PROGRAM  to be saved to
disc.  Every time you save a 128K program, 128K of space will be
used on the  disc  (=  256  sectors).   The  procedure  here  is
slightly different.   The save  will commence  (and if  you have
kept flashing borders  in  your  system  file,  you'll  see  the
borders flashing), but then the program will appear to be frozen
again.'  If the  picture on your  screen (the picture  - not the
border)  has changed, press key Y (= Yes) on the Spectrum: if it
has  not, press key N.   The 128K save will  then be complete in
about 10  seconds and the program will  resume from the point at
which you left it.



                            page 12

If you have loaded the program on drive 1, but wish to save your
snapshot  file to drive 2 - or vice versa - press the CAPS SHIFT
key on the Spectrum at the same time as pressing key 3, 4, or 5.

If  you hit the Snapshot Button accidentally, and wish to return
immediately to your program, press key X on the Spectrum.

When you've saved a Snapshot  file,  press  the  computer  reset
button  once (or in the case of Spectrums without reset buttons,
turn  off the power, then  turn it back on  again and reboot the
PLUS D system).  Then call up  the  catalogue  -  enter  CAT  1.
You'll see  that  your  Snapshot  file  has  been  automatically
labelled "Snap A/B/C" etc.  with  the  letter  of  the  alphabet
dependent  upon the file's position  in the catalogue.  Clearly,
it  would be difficult to remember  the precise contents of your
snapshot file  if this were  the only name  possible.  So you'll
need to give  your  Snapshot  file  an  identifiable  file-name.
First choose a  new name for  the file you  have snapshotted and
then rename it using the ERASE....TO keywords.

Then, to reload Snapshot files, you enter:
    LOAD Dl "Your new file-name" S     (for a 48K file)
    LOAD Dl "Your new file-name" K     (for a 128K file)
    LOAD Dl "Your new file-name" SCREEN$  (for a screen file)
Without the  S, K  and SCREEN$  identifiers, the  Snapshot files
will not load - unless you use the special abbreviated syntax.

Abbreviated syntax

Now that you've  learnt the  basic disc  drive commands,  we can
introduce  you to a much easier way  of loading a file,  You can
just enter:
    LOAD p6
This has the effect of loading the file labelled number 6 in the
catalogue.   If you  use this  command you  don't need  to worry
about the  S, K or  SCREEN$ identifiers to  load snapshot files.
It  also makes it much easier to load code files.  Normally, you
would have to type, for example:
    LOAD Dl "CONFIG1_C"  CODE  40300,1750
-   stating the start address of the file and the number of bytes
used.  Instead, you can now simply enter LOAD p3.   Try it.

MERGE and VERIFY   can also be  used with the  program number in
this way - but ERASE cannot.

Problems?
---------
1.  I've found lots of programs I can't snapshot.
    We can't guarantee 100% success with snapshotting, but we're
pretty  close.  If you're  getting failure with  several of your
programs, there's probably  a problem  with your  equipment.  If
you find  that you can only snapshot  a small number of programs
per disc, this  strongly suggests  a problem  with the  heads on
your disc drive.
2.  I can't copy my Snapshot files using SAVE....TO.
    Quite right - this is a security precaution against Illegal
professional copying of commercial software.


                            page 13

Wild-Card Files

Wild-card  files allow you to  CATalogue, copy (using SAVE...TO)
or ERASE a group of similar files in a single operation.  Let us
imagine, for example, that you have a series of files called:
    numbers1, numbers2, numbers3, numbers4

To erase all of them you can enter:
    ERASE  Dl "n*"
The effect of the star is to  say  that  all  the  rest  of  the
file-name doesn't matter: you wish to erase all files commencing
with "n".   Be careful:  this really  means all  files beginning
with "n".

You could also enter:
    ERASE  Dl "??mb*"
You would then  erase all the  files which have  "-mb-" as their
third and  fourth letters.  The effect  of each question-mark is
to say that "this letter is of no significance".

The same syntax - using ? and * - is available for the SAVE...TO
and  CATalogue commands.   Thus if  you wanted  to copy  all the
files on disc 1 to disc 2, you could enter:
    SAVE Dl "*" TO D2

Or  if you wanted  to copy your  "numbers" files to  drive 2 and
also give them a new file-name, you could enter:
    SAVE Dl "numbers*" TO D2 "figures*"
Note that if  you are using  wild-cards, the new  file name must
have  the same number of characters as  the first - in this case
eight.


Formatting New Discs

Before a floppy  disc is  used for  the first  time, it  must be
formatted.  You can also  format  a  previously-used  disc:  the
effect  will be to wipe the disc clean of information.  You must
therefore be careful  not to  format a  disc which  contains any
files you may wish to keep (and let's say it again - ALWAYS make
back-up discs for important files!).  It is also risky to format
a disc while you are holding a program in the Spectrum's memory,
in case the program is overwritten with format information.

Your original system disc was formatted automatically at the end
of the set-up program.  But to format other discs. make sure the
PLUS D system is booted, and then enter:
    FORMAT Dl

Always make  sure that you  have spare formatted  discs when you
start  work.  Then, if you fill  your original working disc, you
can  easily substitute  a spare  disc without  interrupting your
work in progress.  After formatting a new disc, it's also a good
idea  to copy the PLUS D system file onto it, so that you always
have  a spare system disc available.  You can copy the system to
a new disc by entering:
    SAVE  Dl "+SYSTEM"  CODE  8192,6656

                        ERROR REPORTS
                        -------------

There are  a number  of standard  Spectrum error  messages which
will appear on screen if the command you have typed in cannot be
obeyed.  For full  details, consult  the Spectrum  manual.  When
you are using  the PLUS  D, these  standard error  messages will
continue  to appear, but there are some additional error reports
which  refer specifically to disc  handling problems.  These are
some of the more important you may meet.

Nonsense in Basic

This is  a standard Spectrum error report,  and if it appears as
soon as you start trying to use the PLUS D, it suggests that the
coonnection between the  computer and  the PLUS  D is  not being
properly  made,  so  the  special  PLUS  D  commands  cannot  be
recognised,  Or it may  mean  that  you  have  typed  a  command
incorrectly - try again.

Format Data Lost

This  means that the disc has been  damaged or the file has been
corrupted  - perhaps you've been working too close to a magnetic
field.   You won't be able to access the current file, and other
files  may also  have been  lost.  Copy  any remaining  files to
another disc  immediately.  Try reformatting  the original disc,
and  if there's no permanent  damage, you may be  able to use it
again,  But don't risk storing important files on this disc.

Sector Error

This means  that the information  you've tried to  save has been
corrupted.   You'll need to rewrite the  file and save it again.
But  your disc has not been damaged and need not be reformatted.
The numbers after  the error  message tell  you which  track and
which sector have been  corrupted,  You  should  always  make  a
back-up copy of key files.

If  the  Sector  Error  or  Format  Data  Lost  messages  appear
regularly, you may  have a  problem with  your disc  drive.  The
bead  may be dirty, or  the drive may not  be centring the discs
correctly on insertion.  Try cleaning the heads.  If this fails,
repairs may be necessary.

Disc Write Protected

You  cannot save, erase, or otherwise  modify files on this disc
until you uncover the security  lock  on  the  disc.   (Use  the
security lock on the disc to keep important files safe.)

File Not Found

You are trying to  load, copy,  verify, erase  or rename  a file
which  is not present on the disc.  Check that you have typed In
the  file-name correctly.  Make sure that you have used the file
identifier - S, K or SCREEN$ - if necessary.

                    ADVANCED DISC OPERATIONS
                    ------------------------

Sector  by Sector Copying - Two Drives

    FORMAT Dl TO 2

-  formats the disc in drive 1 (and thus wipes it clean of data)
and copies  the contents of the  disc in drive 2  to the disc in
drive 1, sector  by sector.  BE  VERY CAREFUL NOT  TO FORMAT THE
WRONG DISC.  Because  the  copying is  done a sector  at a time,
the  copying  process  takes  much  longer  than  the  SAVE...TO
command;  but the FORMAT.. TO command will give you a disc which
is identical in every respect to the one which has been copied -
useful if you are investigating corrupt sectors.


Reading and Writing to a Sector

    LOAD @  D,T,S,Address
    SAVE @  D,T,S,Address
These commands are  used  for  reading  from  or  writing  to  a
specified track  and sector on the disc  to a memory location in
the Spectrum memory area, where
    D = the drive number (type either 1 or 2 - not the D)
    T = the track number from 0 to 39 (40 track)
            or           from 0 to 79 (80 track)
    To read the second side on  a double-sided disc drive
            then            128 to 167 (40 track)
            or              128 to 207 (80 track)
    S = the sector number - from 1 to 10
    Address = the start address of any location in the
    Spectrum memory.  Nb: 512 bytes will be used.

Working with a monitor program, this powerful command allows you
to  access a single sector on the disc from Basic.  Particularly
useful  for breaking  into, examining  and modifying  a Snapshot
file.


Using Streams and Channels

i)     OPEN #S; Dl "file-name"  IN  or  OUT

This command  is used to  open a file  on the disc  and attach a
stream  number to it, so that you can print out to or input from
that Stream, where:
        S = Stream number - from 4 to 16 (type the number only)
        D = Dl or D2 (drive number - type D as well as drive no.)
 IN = When you specifically need an input or read file opened
OUT = When you specifically need an output or write file opened

If  you choose not to specify IN or OUT, then the default is the
same  as Interface 1: an input file if the file-name is found in
the catalogue, and an output file if the file-name is not found.
Also available is Microdrive syntax:
    OPEN #S;"m";1;"file-name"


                            page 16

ii)  CLOSE #*S

This  command closes the file and stream opened in  the previous
command.  S  = Stream  number. If  you  do  not type  the stream
number,  then all current open streams will be closed.  Note the
addition of the * to Microdrive syntax.

iii) MOVE is  a command  which moves  a file,  one sector  at a
time, to either another file or a stream.

     MOVE Dl "file-name" TO #S
This  command reads  the file  and outputs  it to  the specified
stream  (where Dl = Dl or D2, and  S = the stream number, from 4
to 16).

     MOVE Dl "file-name" TO Dl "file-name"
This command reads the file and writes it to the second file.

iv)  CLEAR #
This  command clears all open streams  and channels, but it does
not CLOSE a file.

v)   CLS #
This  command clears the  screen and attribute  area, and resets
BORDER, PAPER, INVERSE, BRIGHT, OVER and FLASH.


The Execute File

An excute file is a machine code file occupying up to one sector
length of memory (510 bytes) .  When  loaded  from  disc  it  is
executed (RANDOMISE USR) in the PLUS  D  RAM,  and  not  in  the
Spectrum  memory as other files are.   An execute file gives the
programmer the  ability to  execute utility  routines -  such as
renumbering  a program - without affecting or using the Spectrum
memory.

To save a sector length of memory as an execute file, enter
    SAVE  Dl "file-name",X,Address
where:
    Dl = Dl or D2   (drive number)
    X  = the execute file identifier - just type X
    Address = the location in the Spectrum of the
    machine-code program, which has been assembled
    to run at 3BD6 hex.

To  load the execute file  and run it internally  in the PLUS D,
enter:
    LOAD Dl "file-name" X
or  LOAD p(n)   -   in other words, the normal abbreviated
    syntax for LOAD.

After execution, control is returned to the Spectrum.

Examples  of the use of these more advanced features of the PLUS
D can regularly be  found  in  FORMAT,  often  in  programs  and
routines contributed by PLUS D and Disciple users.

                        USING A PRINTER
                        ---------------


Compatible Printers

The PLUS D  has  a  printer  interface  designed  to  work  with
standard centronics/parallel  type  printers,   You'll  need  to
provide the printer cable, which  may  differ  from  printer  to
printer.  Make sure that at the PLUS D end, the connector is the
standard BBC-type - that it has a 26-way connector.

The   PLUS  D  has  been  set  up  to  work  automatically  with
Epson-compatible    printers.    If   your    printer   is   not
Epson-compatible, you'll need to make  a  few  changes  to  your
System File to make it work.  This is described later.

The  PLUS D offers sophisticated graphics printing capabilities.
Obviously, daisy  wheel printers,  which cannot  print graphics,
will  not be able to  make full use of  the PLUS D's facilities.
There are also  a small  number of  older dot-matrix  printers -
those which print  their characters  on a  7-dot rather  than an
8-dot matrix - which will not print graphics with the PLUS D.



Setting up your Printer

If  you are using a disc drive and have already set up your PLUS
D System File (see page 4), then your printer will automatically
be ready for action every time you boot up the system.

If you don't yet have a disc drive but wish to use the PLUS D as
a stand-alone printer interface, you may do so.  If your printer
is Epson-compatible, you should be able to plug the printer into
the  PLUS D (with the computer power off, of course), switch the
system  on and then type  in POKE @ 11,0  to turn the centronics
interface on.

If  your printer is not Epson-compatible then you'll need to use
the  program on the System Cassette.  Connect the printer to the
PLUS D  and turn it on.  (In this  case, you don't need to enter
POKE  @ 11,0.)   Then load  the System  Cassette program  in the
normal way (LOAD "").

When the program  has  loaded,  you'll  be  asked  a  series  of
questions.   The first questions relate to  use of a disc drive.
Press ENTER  to bypass each of these  questions and then press Y
(= Yes) when  asked "Do  you want  to use  the PLUS  D's printer
port?"  At this point, you'll find  the answers to the questions
in your printer  manual.  If  you find  that the  printer manual
defeats you, please contact INDUG, the Users' Group, for help.

Finally, there'll be a series of questions referring to the disc
drive  again.  Answer No  to all these  questions.  Printing can
now commence.



                            page 18

Starting to Print - LPRINT, LLIST and SAVE SCREEN$ 1

LPRINT  and LLIST  have exactly  the same  meaning as  PRINT and
LIST,  except that instead  of making information  appear on the
screen, they send it  to your  printer.  To  see how  they work,
enter the following program - but first, check that your printer
is attached  to the PLUS D and turned  on, and that you have set
up your printer as described in the previous paragraph:
    10  LPRINT  "This program"
    20  LPRINT  "prints out the character set"
    30  FOR n=32  TO  255
    40  LPRINT  CHRS  n;
    50  NEXT  n
    RUN

When  you run the program, the  LPRINT command sends the heading
and the list of characters directly to the printer.

Now enter LLIST - and the listing of your program is sent to the
printer.

Then enter  LIST to restore  the program listing  to the screen.
Finally,  enter SAVE SCREEN$ 1.  (Note that if you are using 48K
mode on your  computer, both SAVE  and SCREEN$ must  be typed in
using  the Spectrum keywords.)  With  this command, the contents
of  your  screen  are  copied  (technically,  "dumped")  to  the
printer.

SAVE SCREEN$ 1 is a particularly powerful command: if you've set
up  your system to print graphics,  you can dump screen pictures
to  your printer.  There's also a  SAVE SCREEN$ 2 command, which
will dump a screen picture to  the  printer  in  a  much  larger
format: with  this command, you'll find  that the print-out will
be sideways  down the page, and that  the various colours on the
screen will be interpreted as shades on the print-out.  But, the
SAVE SCREEN$  2 command will only  work with Epson-type printers
which recognise  the ESC *  code for bit  image graphics.  INDUG
may be  able to help if your printer  is unable to do the larger
screen-dump.

Note  that you can also use SAVE SCREEN$ instead of SAVE SCREEN$
1.

Note  also a peculiarity of Spectrum Basic.  If you have written
a program listing on screen, you cannot dump the screen directly
to your printer.  First you have to enter LIST: then you can use
SAVE SCREEN$ 1.  Or, faster would be to write your program, then
simply enter LLIST.

When printing, you can also use  the  commands  TAB  and  AT  to
position your text at  a certain  point on  the printed  line or
page.  Try these two examples to see how the commands work:    -
    LPRINT  TAB  8: "This line is indented"  ENTER
    LPRINT  AT  4,5: "This line is less indented"  ENTER
In  example 1, you start printing at character position 8 on the
current line; in example 2, you start on line 4 at position 5.



                            page 19

Snapshot Printing

The  SAVE SCREEN$ 1 command allows you to dump the screen to the
printer -  provided you are able to  enter a Basic command.  But
what  happens if, for example,  you are in the  middle of a game
and  you want to print the current  screen but you can't exit to
Basic? With the PLUS D  you can still do your screen dump, using
the Snapshot Button.   This  use  of  the  Snapshot  Button  has
nothing to  do with  the disc  drive -  and in  fact you  can do
Snapshot prints even  if  you  are  not  using  a  drive.   This
facility  offers exciting new possibilities to games players: in
an  adventure game, for example, you can print out the screen at
each new  location, gradually building up  a complete picture of
all the available screens.

To  experiment with Snapshot printing,  load a normal commercial
program, preferably a  game  with  good  graphics  to  show  the
facility at  its best.  When you wish  to print a screen, simply
press  the Snapshot  button -  in the  same way  as if  you were
taking a  Snapshot save.  As  usual, the program  is paused.  If
you  then press key 1 on the Spectrum, you will send a 32-column
screen  dump to the printer.  If instead  you press key 2 on the
Spectrum  (and   you  have  an   Epson-compatible  printer  that
understands the ESC  *  code),  you  will  be  able  to  send  a
large-size screen dump to the printer  -  just  as  if  you  had
entered the command SAVE SCREEN$ 2.

When printing is complete, the  program  will  resume  from  the
point at which you left it.


Changing the Layout of your Printed Page

With an Epson-compatible printer, the PLUS D's printer interface
has been set up to the following standard:

    Line-length:    80 characters per line
    Line-spacing:   1/6" (=12/72" or 6 lines per inch) between
                    lines.
    Line-feeds after carriage return:   1 line
    Left-hand margin spaces after carriage return:  0
    , #, and  symbols set to be printed:  Yes
    Density/size of graphics:  Single density graphics
    Character pitch:  Pica  (= 10 characters per inch)


If you wish to  change these  variables, you  can use  a special
PLUS  D command - the POKE @ command.  Every POKE @ command must
be followed by  a number, which  states which variable  is to be
changed.   For example, the POKE @ 5 statement is concerned with
line  length, while the POKE @ 7 statement is concerned with the
spaces between  lines.  The number  is then followed  by a comma
and  another number, which is the variable you wish to set.  For
example, POKE @ 5,40 would set your line length to 40 characters
per line.




                            page 20

The POKE  @ statements are  temporary settings, and  if you turn
off  your mains power, you'll need  to reset them.  However, the
PLUS D retains POKE @ commands if you simply reset the computer:
you'll be able to continue with the same variables in use.

This is how  to  change  your  page  layout  using  the  POKE  @
commands:

Line Length:
    POKE @ 5,n  (n = 0 to 255)  default 80
The  number you type in for the  variable (n) will be the number
of characters per line - provided your printer can cope with the
number you've typed.

Line-Spacing:
    POKE @ 7,n  (n = 0 to 255)  default 12
The number (n) you type in will set the spacing between lines in
increments of  n/72" - thus 12 is 12/72"  or 1/6" (= 6 lines per
inch).

Line-Feeds after a Carriage Return:
    POKE @ 8,n  (n = 0 to 255)  default  0
The number you type will be the number of line-feeds.

Left-hand Margin Spaces after Carriage Return;
    POKE @ 9,n  (n - 0 to 255)  default  0
The number you type will be the number of spaces before printing
begins in the left-hand margin.

Printing , # and  as graphics symbols:
    POKE @ 10,n (n = 0 or 1)    default  1
Type 1 if you need , # and . Type 0 if you don't want them.

Printing from a Commercial Word Processor

Commonly,  commercially-produced   word  processors   and  other
"serious" software have  a special  printer driver  which allows
you to send your work  to  a  printer.   Much  serious  Spectrum
software has now been  modified  to  work  with  the  Disciple's
printer  interface.  The Disciple was  the PLUS D's predecessor,
and if your software allows you a Disciple printing option, this
will also work with the PLUS D.

Occasionally  though, you  may find  that a  Disciple or  PLUS D
printer  driver is not offered.   If so, and if  when you try to
print, you get  unsatisfactory  results  (a  common  symptom  is
question-marks appearing in  the  left-hand  margin),  you  will
usually  be able to solve the problem by finding the part of the
program-listing which sends data to the printer and preceding it
with the  line: POKE @  6,1.  Then, when  the printing finishes,
enter the line POKE @ 6,0.

What's happening here  is that, by  entering POKE @  6,1 you are
allowing codes embedded in the  software  to  be  sent  directly
through  to the printer without being intercepted by the PLUS D.



                            page 21

POKE @ 6,0 allows the  PLUS  D  to  take  over  again  when  the
software's printer driver is no longer in operation.
(Programmers  note that POKE @ 6,1  allows the printer driver to
output  directly to the printer the absolute value of the code 0
to 255.  Note also that under normal circumstances, if a control
character is to  be sent to  the printer using  LPRINT, then you
must precede it with CHR$ 27 - even when you want to output CHR$
27.  Thus, to output CHR$ 27, CHR$ 65, CHR$ 40 you would enter:
    LPRINT CHR$ 27;CHR$ 27;CHR$ 27;CHR$ 65;CHRS 27;CHR$ 40
But  if you enter  POKE @ 6,1  first to release  PLUS D control,
then you  will not need  to precede the  control characters with
CHR$ 27.  When you've finished, don't forget to return to POKE @
6,0.


Other types of printer

If  you are using a serial printer, you cannot connect it to the
PLUS D, but you can continue  to  use  the  PLUS  D  as  a  disc
interface.   Your serial printer can  be connected directly into
the PS232 port on the Spectrum Plus Two as usual; or if you have
a  separate RS232 interface, use a Y connector so that it can be
connected to the computer at the same time as the PLUS D.

Similarly,  the Sinclair ZX Printer can be connected at the same
time as  the PLUS D by using a  Y connector.  (Don't try to plug
the  PLUS D in behind the ZX printer: the printer's through port
does not carry through the full signal, which the PLUS D needs.)

In both  cases, when the System File  asks whether you are using
the PLUS D's centronics printer port, answer No.

You  can also "turn off" the PLUS D's centronics printer port by
using  another POKE @ statement.  POKE @ 11,1 leaves the printer
channel  unchanged by  G+DOS: it  assumes that  you are  using a
serial printer or  the ZX printer.   POKE @ 11,0  makes the PLUS
D's centronics printer channel active again.


Ouestions/Problems
------------------
1.   I can't  even find  the initialisation  code in  my printer
manual.
    If  you can't  find this  code, try  the code  for Carriage
Return,  which is almost  universally 13 (in  decimal), or enter
128 so  that no codes are sent.   Remember that if you're having
real  difficulty in understanding  your printer manual, INDUG is
likely to have had previous experience with your printer.

2.  Are there other POKE @ commands?
    Yes.   If  you're  a  serious  programmer,  needing  fuller
coverage of these -  or details  of the  PLUS D's  command codes
(used in  machine  code  routines  to  effect  control  of  disc
subroutines),  please talk to the Users' Group.  There's regular
coverage in FORMAT.
