Conchess, a series of modular chess computers by Consumenta Computer.
Hardware development by Loproc (Germany), manufactured at Wallharn Electronics
(Ireland). The core people involved were Ulf Rathsman for the chess engine,
and Johan Enroth. After Consumenta went under in 1983, the Conchess brand was
continued by Systemhuset, Enroth's company.
TODO:
- dump/add princhess module
- dump/add plymate original 2MHz module
- dump/add concplyv library module (L/L16 don't work, manual says it has its own add-on)
- concplyv unmapped reads/writes
- verify irq/beeper for concplyv, though it is probably correct
- official rom labels for concply5, concply8
-------------------------------------------------------------------------------
Hardware notes:
Chess boards released were Escorter, Ambassador, and Monarch, each should be the
same hardware, they just differ in size and material.
- TTL, 2 module slots
- 16+64 leds, 16 buttons, reed sensors for magnet chesspieces
All chess modules appear to be on similar PCBs, with room a 6502/65C02,
and 8 ROM/RAM chips.
For the newer programs, higher clocked versions were also available, the CPU speed
was labeled on a sticker on the module (eg. A2/5.5MHz). A German redistributor
named them "S"(speed) or "T"(top speed).
A0 (untitled standard pack-in module):
- SY6502A @ 2MHz (4MHz XTAL)
- 3*8KB ROM, 4KB RAM(2*TMM2016P)
- TTL, beeper
note: XTAL goes to 4020, 4020 /2 goes to CPU clock, and other dividers to
IRQ and beeper. On A0, IRQ is active for ~31.2us.
A1(P) + A0(M) (Princhess, aka Glasgow)
- dual-module, each module has its own 6502 - need verification, more likely
2nd module has no CPU (according to the manual, A0 is modified and won't
work stand-alone)
A2(C) (Plymate, aka Amsterdam)
- R65C02P4 @ 5.5MHz (11MHz XTAL) (5.5MHz version)
- 32KB ROM, rest similar to A0
A3 (Plymate Victoria)
- W65C02S8P-14(14? probably replaced chip from a repair) @ 6.144MHz (12.288MHz XTAL)
- 32KB ROM, rest similar to A0
Library modules:
- L: small PCB, PCB label: CCL L-2, 8KB EPROM no label
- L16: 2*8KB EPROM (have no photo of PCB)
