CXG Computachess III, Chess King Triomphe, RadioShack 1650 Fast Response, Fidelity Genesis, CXG Sphinx Comet
I assume same ROMs for all, only Crystals vary a little bit.

RadioShack 1650 Fast Response: Concord II, has the 0609V171 MCU

CXG Computachess III: pretty sure it's HD6301V1C42P
Fidelity Genesis: should also have the HD6301V1C42P

CXG Sphinx Comet: wiki says it has a V1, but I'm not sure.

Chess King Triomphe: interesting, here is a photo of the inside http://www.chesscomputeruk.com/html/..._triomphe.html

I had that computer at home, I attach a better quality photo.

Best,

Hi,

die 2 neuen Saitek/SciSys-Geräte (Chess Companion II und Explorer Chess) sind jetzt auch in CB-Emu implementiert -
vielen Dank an 'hap' und Sean Riddle!

Wie üblich bei komplett neuen Modellen mußte ich sowohl Treiber als auch Layout wieder ziemlich ändern, damit sie unter der alten MAME-Version 0.220 noch funktionieren.
Beide Engines benutzen exakt das gleiche ROM, sind also vom Programm her identisch. Nur die Tasten (und teilweise auch deren Bedienung) sind etwas unterschiedlich. Daher war es auch nötig, für beide Engines unterschiedliche Plugins zu schreiben (übrigens beherrschen sie auch den Setup- und Edit-Modus).
Bie meinen Tests hat alles funktioniert, aber natürlich wären weitere Testpartien oder Stellungstests zur Sicherheit nicht schlecht.

PS: Übrigens, falls jemand den 'Saitek Senator (Executive) Chess' in der Liste sucht - der findet sich jetzt unter 'E', da ich ihn in 'Saitek Executive (Senator) Chess' umbenannt habe. ;)

Question for hap:
There's one thing I don't understand with these 2 devices: they have different key codes (ports&bits), although using exactly the same ROM program - how is this possible?
Example:
Port "IN.2" bit 0x02 is "Multi Move" for the ccompanion2, but the same port&bit is "Take Back" for the expchess!?
So if this key with port "IN.2" bit 0x02 is pressed, how can the same program know, whether it should switch to 'multi move' mode (when I'm running ccompanion2) or just 'take back' the last move (when running expchess)??
Looking at your driver I don't see any differentiation between these 2 engines - apart from the layouts and the input ports they use exactly the same machine configuration!?

Grüße,
Franz

There's a note in the driver about that: "Explorer Chess and Chess Companion II / Concord have the same MCU ROM, pin P23 is either VCC or GND to distinguish between the two."

So, SciSys has put the 'sequel' to Travel Sensor and Companion on the same rom.
See the resemblence:

Ah, these are hardware descriptions in the driver that I usually don't read, because I wouldn't understand them anyway. :D

Hello,

The CXG Star Chess is emulated.

Star chess has many 100% clones :
CXG Entreprise S (1984),
Schneider Enterprise S,
CXG Computachess III,
Mephisto Merlin 4K,
CXG Sphinx Comet,
CXG Super Computachess,
CXG Crown,
CXG Sphinx Galaxy 2,
Fidelity Genesis.

Cordially.

        db      $FD, $44, $FE, $10  ;

Hacking is possible by adding 2 keys and put the pin 3 of the port 2 at Vcc.

In https://hiarcs.net/forums/viewtopic....301xl&start=45 there is a long study about Chess King Triomphe.

From "Summary of Deviations" by spacious_mind (Sat Oct 21, 2017 6:26 pm)
http://spacious-mind.com/forum_repor...st_summary.gif

it seems that :

Chess King Counter Gambit 2 MHz
Yeno 301 XL 2 MHz
Chess King Triomphe 1 MHz

are the same program of an unknown programmer, and probably not from Kaare Danielsen.
It seems also that is the best 4K program (better than Star Chess/Enterprise...).

Cordially.
