|
||||
SC6 Hardware notes:
|
||||
- PCB label 510-1045B01
|
||||
- INS8040N-11 MCU, 11MHz XTAL
|
||||
- external 4KB ROM 2332 101-1035A01, in module slot
|
||||
- buzzer, 2 7seg LEDs, 8*8 chessboard buttons
|
||||
|
||||
released modules, * denotes not dumped yet:
|
||||
SC6 released modules, * denotes not dumped yet:
|
||||
- *BO6: Book Openings I
|
||||
- *CG6: Greatest Chess Games 1
|
||||
- SC6: pack-in, original program
|
||||
|
||||
SC6 program is contained in BO6 and CG6.

|
||||
MSC hardware notes:
|
||||
- PCB label 510-1044B01
|
||||
- P8049H MCU, 11MHz XTAL
|
||||
- 2KB internal ROM, module slot
|
||||
- buzzer, 18 leds, 8*8 chessboard buttons
|
||||
|
||||
I/O is identical to SC6.
|
||||
|
||||
MSC released modules, * denotes not dumped yet:
|
||||
- CAC: Challenger Advanced Chess
|
||||
- *CBO: Challenger Book Openings
|
||||
- *CGG: Challenger Greatest Games
|
||||
|
||||
The modules take over the internal ROM, by asserting the EA pin.
|
||||
|
||||
2 MSC versions exist, they can be distinguished from the button panel design.
|
||||
The 2nd version has rectangular buttons. The one in MAME came from the 2nd one.
|
||||
|
||||
TODO:
|
||||
- MSC MCU is currently emulated as I8039, due to missing EA pin emulation
|
||||
- msc internal artwork (game works fine, but not really playable at the moment)
