What is structure of rom files bigger than 32kB ?
Exist 64kB/128kB and 256kB roms for ZX emulators.
32kB roms contain 128ROM + 48ROM.
64kB roms contain also this roms + trdos + ???. Layout of this bigger roms is same for all emulators ? Different ZX clones use same rom layout ?
Any info about bigger roms than 64kB ?

ROM, over 64K in the ZX Spectrum clone produced in the ex USSR did not apply. ATM and Sprinter are not clones of ZX Spectrum. This is a ZX Spectrum compatible computers such as SamCoupe.Цитата:

First 64kB contain:

PROF-ROM is used only on Scorpion computers ?
Kramis - this ROM has the technological purpose and is only used when setting up your computer.

It's my new project in development:
PROFI INTERFACE for ZX128+2:
- contain CPU Z80, FLASH EPROM 512kB , 1MB SRAM(+battery) , CPLD, extra NMI button
This interface can emulate memory paging of russian ZX clones (ZX PROFI, PENTAGON, SCORPION, etc...). TRDOS rom mapping will supported (work only with ramdisc in 1MB memory). All paging ports will readable, all features will changeable. For example - part of extended ram memory can emulate rom (will set to low 16kB as zx rom replacement with write protect). This enable modify zx roms, trdos , nmi menu, etc.....
Actually I must create content for this 512kB FLASH EPROM. My idea is join 4x 64kB rom (first 256kB) + one PROF-ROM (second 256kB).
I know, see my page:Цитата:

PROFI INTERFACE will compatible, but more powerfull :v2_yahoo:
New NMI button will jump to extra NMI menu without rewriting memory on stack pointer (it's planned feature). I/O adress space can be mirrored to extra memory and user can read from memory last writed values to ports :v2_scare:
Possibility block extra memory for users (128kB only) and enable extra memory (1MB) only for trdos rom (ramdisc will protected).
Advanced memory paging in low 16kB (as rom replacement) = DivIDE emulation

This is only example of possibility. On real PROFI INTERFACE willl extra decoder for all paging ports.

(if will any free space in CPLD then can be implemented also SAM COUPE memory paging)
and emulation of:
MB02 memory
DivIDE memory
DivIDE PLUS memory
CP/M LAMAC/TROLLER
I will read only state of this ports, but from different adress than 1FFD or 7FFD :v2_biggr: This interface is designed only for ZX Spectrum 128+2(grey model) - ULA in this computer not any paging port, this part is used out of ULA (my PROFI INTERFACE and 74LS174 on board of +2)Цитата:

Pages 4 - 7 ? It's not designed for +2A/+3 computers, but only for +2. ZX128+2 use ULA contended pages 1,3,5,7 and fast ram pages 0,2,4,6. Only pages 5 and 7 is in ZX ram. Other memory is in extra sram. Reading memory is always from sram.Цитата:

Thank you, I understand the architecture.

I propose as a common standard reader ports #1FFD, #FE, #7DDF for all clones, use the address #BDFD, #BFDD, #BFFD. I propose that these ports are used as a cross-platform standard. When using MB02, DivIDE and other devices have their own port addresses, ports #BDFD, #BFDD, #BFFD will have to duplicate them.Цитата:

And why this adressation ?
#BDFD/48605 1011110111111101 10xxxx0xxx1xxx01 rd #1FFD
#BFDD/49117 1011111111011101 10xxxx1xxx0xxx01 rd #FE
#BFFD/49149 1011111111111101 10xxxx1xxx1xxx01 rd #7FFD
Better way is use identical low 8bit adress for all this ports. This eliminate collisions with kempston joystick and original KEMPSTON MOUSE (if A5=0). Low adress will always #FD (with 8bit full adressation) and port type will selected via other adress lines in high byte)
Yes, it is possible:Цитата:

#BAFD/47869 1011101011111101 10xxx0x0xxxxxx01 rd #1FFD
#BBFD/48125 1011101111111101 10xxx0x1xxxxxx01 rd #FE
#BEFD/48893 1011111011111101 10xxx1x0xxxxxx01 rd #7FFD
VELESOFT, that's version is compatible with K-MOUSE Turbo 2008. You agree to change the decoding in the GAL and add #FE and #1FFD?
K-MOUSE TURBO 2008 use this port:Цитата:
Сообщение от БК-0010
rd7ffd = 65247(#FEDF) 1xxxx1x0 11011111 ( return data of port #7FFD )
A7-A0 must be set to 11011111 = this is incompatible with your:
#BEFD/48893 1011111011111101 10xxx1x0xxxxxx01 rd #7FFD
In K-MOUSE is not free space for change(=add) new port adress. :v2_confu:
K-MOUSE not return real value of port 7FFD, only last writed value !!! (ignore reset)
If you need read real values of 7FFD port, please use different port for reading than in K-MOUSE. :v2_wink2:
Your port #BEFD/48893 1011111011111101 10xxx1x0xxxxxx01 is OK :v2_smile:
White space may occur if you delete the second address for reading the port #7FFD. The conflict, which may be possible while reading from two K-MOUSE Turbo 2008 does not arise, because their data bus is connected through resistors 150 + 150 = 300 ohms. Therefore, the second address for reading the port #7FFD not needed.Цитата:

This is not a problem. Let the master reads the port #7FFD, a slave read port #1FFD or #FE. Get 100% detection of the master / slave.Цитата:

K-MOUSE can use only adress lines A15, A10,A8-A0. It's impossible detect writing to port 1FFD. For correct 1FFD writing must be used also adress lines A14-A12 :v2_frown:Цитата:

K-MOUSE is designed as single interface with possibility switch to slave ports. (all features is same as in master). Reading port #FE will possible only after source code modification, but this mouse can't use switching between master/slave and will fixed as slave only or master only device.
Yes, I propose to change the appointment jumper master / slave. In this case it is necessary to make K-MOUSE Turbo 2008 two modifications - master or slave. In this case, the jumper will have such appointments:Цитата:
Сообщение от VELESOFT
- To master K-MOUSE Turbo 2008 - #7FFD/#FE;
- For the slave K-MOUSE Turbo 2008 - #1FFD/#FE.
- To master only - #7FFD(ZX48/ZX+128/+2, +2a/+3) or #FE(Timex);Цитата:
Сообщение от VELESOFT
- For the slave, master is present - #FE(ZX48/ZX+128/+2, +2a/+3) or #7FFD(Timex).
These changes will allow more flexibility to configure the ports and to meet the peculiarities of different computers such as ZX48/ZX+128/+2, +2a/+3, Timex.

Ability to read ports #FE and #7FFD will be able to maintain the image of the computer memory in snapshot.
Adressation of port #FE is different o ZX Spectrum models and on TIMEX.Цитата:
Сообщение от БК-0010
ZX use adressation A0=0 and TIMEX use full adressation A0=0 + A1-A7=1.
Adressation of port #7FFD is also different on ZX128,+2A,ZS Scorpion and russian ZX clones. K-MOUSE detect port #7FFD on real ZX 128/+2 only (accept A1=0, A15=0).
ZX128+2A and some russian ZX clones use this adressation:A15=0,A14=1,A1=0
ZS Scorpion use very different adressation.
Reading port 7FFD from K-MOUSE TURBO 2008 return always true value only on ZX models/clones with original adressation (use only A15=0 and A1=0 as ZX128/+2 and Pentagon)
Any write to port 1FFD rewrite port 7FFD in K-MOUSE TURBO (K-MOUSE ignore A14,A13,A12) = reading is usable only on ZX128/+2 and Pentagon.
My idea: create new CPLD based port decoder for reading this ports. CPLD will configurable (contain switches for set ZX models/clones).
Why create a new design, if sufficient to change the contents of the CPLD K-MOUSE TURBO 2008? My idea: create a CPLD update for K-MOUSE TURBO 2008. At Christmas, users using the K-MOUSE TURBO 2008 will be happy to update this device. :)Цитата:

For Timex and ZX Spectrum, you can create different CPLD.
K-MOUSE can detect without hardware modification only port 7FFD (from ZX bus is connected to CPLD only A15, A10, A8, A7-A0). Exist software using uncomplette port adressation - for example:Цитата:
Earlier this for you was not an obstacle. So in K-MOUSE TURBO 2008 for the ZX Spectrum +2a/+3 this feature will not be used.
OUT 0,page or OUT 253,0 - not work on SCORPION, SPRINTER, +2A, +3, but work on PENTAGON 128/512, ZX128,ZX128+2
Also OUT 252,xx on real ZX128/+2 write XX value to ULA port FE and parallel to paging port 7FFD. This feature is used for set border colour and videoram switching in tape loaders :v2_wink:
K-MOUSE is only limited with 34 user I/O pins. I can write new firmware with readable different ports, but must be modified schematic or real interface with wires. Will replaced some features with other readable ports, or replaced CPLD with bigger SMD version (64 or 100 pins).
