Notes:
|
|
------
|
|
- For testing purposes, Black Widow boards can be plugged directly into a
|
|
Gravitar harness. If you want to actually play the game, you'll have to
|
|
add 4 extra wires at P20:[8/9/K/L] for the extra control panel inputs.
|
|
- The "CABINET" pin (P20:R) is potentially interesting. I haven't played
|
|
with it, but suspect that if you tied it to GND (or left it open), you
|
|
could play the game on a cocktail cabinet.
