* The above listed joystick maneuver to enable Pac-Man will still play a tone, but
the effect (if any) is unknown.
* CPU is a Z8S18020VSC (20MHz part), OSC is 73.728MHz
Note: The "correct" size of the roms are 27C020 for the program rom and 27C256 for the
graphics rom. However genuine boards have been found with larger roms containing
the same data with the extra rom space blanked out.

the Z180, but the cpu core doesn't support that yet.
* Is the clock divide 3 or 4?
