-TODO:
- what's VIA PB0 for? game toggles it once per irq
- identify XTAL (2MHz CPU/VIA is correct, compared to video reference)
- add display DP segment (unused in boris25), and what about AP segment?
- verify cartridge pinout, right now assume A0-A14 (max known cart size is 24KB).
-  Boris/Sargon cartridge is A0-A11 and 2 CS lines.
- auto-switch keypad overlays? no need for it yet
- (probably won't) add chesspieces to artwork? this machine supports more board
-  games than just chess: checkers, reversi, and even a blackjack game
