TODO:
- figure out why chessmsta won't work, for starters it assume z80 carry flag is set at poweron?
- the HALT button does not work as it should: it stops the computers calculation
(the board LEDs go OFF and the CM's LED goes ON), but the machine doesn't return any move (as it should)
- a better artwork
