Novag Super Nova & related chess computers. I believe the series started with
Primo. The chess engine is by David Kittinger.
NOTE: nsnova does an NMI at power-off (or power-failure). If this isn't done,
NVRAM won't work properly (supremo doesn't have NVRAM).
TODO:
- NMI on power-off switch, it sets 0x14 bit 7 for standby power (see below)
- add nvram, MCU is missing standby power emulation
- if/when MAME supports an exit callback, hook up power-off NMI to that
- beeps are glitchy, as if interrupted for too long
- nsnova serial port isn't working, MCU emulation problem?
- nsnova unmapped reads from 0x33/0x34
