I just got back from trying to fix a cocktail cab that I made and sold locally in 2004. It has an IPAC2 connected via PS/2. It's been working fine, but now gives 2 quick flashes followed by 12. According to the Ultimarc website, it's a bad P2 SW4. This particular machine doesn't use that switch. Each player has a 4 way stick and 1 fire button. There is also a coin slot, P1 and P2 start.
I verified the wiring by using a multimeter on the IPAC, one lead on GND and the other on each input - everything checked out fine. I then unplugged all wires from the IPAC so the only thing connected was the PS/2, but still get the same error flashes. There's no indication of blown components on the board. As a last resort I removed and reseated the main chip on the board, but still get the same codes.
I'm having the guy who owns the cab email Andy at Ultimarc, but I thought I'd post here and ask if anyone has seen similar behaviour before.
Thanks!
