I can't find any indication that the Tasc system program detects R40 and changes "R30" to "R40", it looks to me like "R30" is hardcoded in the ROM. CBF which version of R40 ROM did you receive? Was it Gideon or King?

If it's Gideon, there's a photo here with Gideon running on a R40: https://www.schach-computer.info/wiki/i ... _R40-6.JPG
It still says "R30" there and the system program is the same version as on King 2.20.

It was the King 2.50 ROM, but absolutely identical to the R30 ROM that we already had.
The friend who sent me this R40(?) ROM owns a Tasc R40 and said, that it was indeed
dumped from the ROM inside his R40!?

About the R40 detection: could it be, that the slightly different ARM-CPU chip in the R40 (you mention this
in the tasc.cpp source file) could be used to distinguish between R30 and R40?

There's an ARM opcode for detecting the CPU version, it's not used in tascr30.

Well, than it will remain a mystery.
If I would know where in the ROM this text "R30" is located, then I'd probably make an extra
ROM version for the R40 showing "R40" in the system info.

"R30" is in multiple places, but changing it will break the game (probably a ROM checksum test)

External artwork example for MAME:

It's Volodymyr's artwork for Designer 2100 Display. I modified it to make it work on MAME.

It's back! At zero cost. No expensive plugin card needed any longer. Wizard Franz Huber did it again, he now has emulated the hardware miracle of the early 90's.

ChessMachine ISA card emulator is written by me, not Franz :P
No, actually, did you know that wizard Franz not only wrote the emulator but the chess engines too? Yes indeed, he provides the ChessMachine emulator package that must mean he wrote Gideon and The King, right? I thank the Franz the great wizard for Gideon!

Nooooo, you will not stop me from spreading the real truth that Franz wrote Gideon.
