Control Panel Wiring

Wired up the Control Panel this weekend. I started by wiring the Ground on each microswitch and split this into two different circuits, one for Player 1 and the other for Player 2. Next I wired each Button to its corresponding connection on the IPAC.

Once all the wiring was done I hooked up the Control Panel to the Computer via the PS2 cable and booted, and what I got was an Keyboard Error. So for the next couple of hours I troubleshooted this until I found the source of the Error: A FAULTY connector on the IPAC. If I had the COIN2 wired then I would get the error but without the connection the Keyboard is detected correctly and boots.
