TODO:
- - Coinage Dip Switch doesn't match the readme? Also there are wrong coin insertions even
- with the bit impulse macro. There are chances that there's a circuitry which controls
- both...
+ - Video emulation requires a major conversion to the HD46505SP C.R.T. chip (MC6845 clone)
+ - It's possible that there is only one coin chute and not two,needs a real board to know
+ more about it.
How to play:
- A to D selects a card.
