RAMDISC in TRDOS

[VELESOFT]

My idea:
create official WEB for TRDOS roms and documentation and release all possible trdos versions.

This page contain different trdos rom versions, but without any documentation

http://www.zxspectrum.it/_TR.htm

[alone]

Where I must modify code in TRDOS rom, if I need set ramdisk on drive A: ?
A = ramdisc
B = fdd B
C = fdd c
D = fdd d

Or set ramdisc in all drives ?
A = ramdisc
B = ramdisc
C = ramdisc
D = ramdisc

Open DOSprogs.H and look for TCH1 label. Replace CP #03 with your value.

Your archive contain my version of BETACRACK trdos rom.
This is my original BETACRACK directory with all sources and new ENGLISH info:
http://velesoft.speccy.cz/other/betacrack.zip



ENGLISH INFO FOR BETACRACK ROM:

new TRDOSu 5.03 version (BETACRACK).
TRDOS503EXTRA.ROM is trdos rom with monitor. For monitor activation
you must press SHIFT if software access to disc via call #3D13(15635).

NEWS:
- new test of 128kB page number
- test 128kB memory page will call only after press key 1 or 2
  in monitor
  Key 1 test 128kB page and set first videoram (show monitor)
  Key 2 test 128kB page and set second videoram (show screen in vram 2)
Some TRDOS software can call trdos services with active 2nd videoram.
After start monitor will show only 2nd videoram and for show monitor
you must press key 1. Before exit from monitor press key 2 for return
with correct screen.

TRDOS503AUTO.ROM is identical trdos version, only after call trdos
service 5 always show monitor. For other services you must press SHIFT.

All sources for assembler PROMETHEUS 128 is included. 
In 128kB page 0 is from adress 49152 original TRDOS 5.03 with
included ZX font at adress 62000 a with monitor.
File "meziprom11auto.SNA" is runnable source code(assembly to
adress 45000 (???).
File "meziprom11romauto.SNA" is source code with modified adress
ORG,PUT and ZNAKSADA, needed for final assembly to 128kB page 0 with
TRDOS.(in page 0 is yet modified TRDOS, you can save this trdos rom
as CODE 49152,16384.

TRDOS503ALL.ROM is next version, but start monitor after call any
trdos service via #3D13

Next planed trdos versions:
- start monitor also at next rom adress
- memory editor
- DEC/HEX support in monitor
- show memory contents from (AF),(HL),(DE),(BC),(IX),(IY),(SP)
- after LOAD block form FDD will possible export this file to
  tape.
- test 128kB memory page will work also with pentagon 512
- new font 8*4 pixels=64 chars on line
- this modifications will implemented to trdos 5.04 version

Open DOSprogs.H and look for TCH1 label. Replace CP #03 with your value.

I rewrite on TRDOS 6.10E instructions:
LD A,(#5CF6) + CP #03
to
LD A,(#5CF6) + CP #00

This version of TRDOS contain this code 4x :
#0833
#3800
#3912
#3924

After start work ramdisk in drive A.
After switch to drive B or C will FDD tested, but D show OK without testing drive D. It's correct ?

This is original TRDOS 6.10E + modified (ramdisc in A):

Извиняюсь за оффтоп, но в 1993 году я сделал RAMDISK, ориентированнный только на Ассемблер GENS-128.
В принципе, ramdisk работает в любых ситуациях.
Попробуйте скачать GENS-128 с моего сайта
