I’ve made a really basic Missile Command Jamma Adaptor, to make it easier to test the PCB on a supergun, rather than in cabinet itself. I only connected the following Missile Command pins:

A – GND
C – 12v
L – Blue
M – Green

2 – +5
10 – Red
18 – Comp Sync
19 – -5

Please note the above has the +12v on Jamma pin 6 going to Missile Command pin C. Usually the +12v is on pin 20 on Missile Command, but pin C is also +12v, so this is fine
