Novag Super Constellation Chess Computer (model 844)
Hardware notes:
- UMC UM6502C @ 4 MHz (8MHz XTAL), 512Hz? IRQ(source unknown?)
- UMC UM6502C @ 4 MHz (8MHz XTAL)
- 2*2KB RAM TC5516APL-2 battery-backed, 2*32KB ROM custom label
- TTL, buzzer, 24 LEDs, 8*8 chessboard buttons
- external ports for clock and printer, not emulated here
