Switch settings:
Notes:
1) Facing the CPU board, with the two large IDC connectors at
the top of the board, and the large and small IDC
connectors at the bottom, DIP switch #1 is upper right DIP
switch, DIP switch #2 is the DIP switch to the right of it.
2) Facing the Sound board, with the IDC connector at the
bottom of the board, DIP switch #3 (4 bank) can be seen.

Issues:
- it doesn't work!
- sprite position and scaling
- collision detection
- character colors (mising a PROM I think)
- background colors -- this is most likely a bug
- speed
