So after years of being in this hobby, I finally picked up my first Ms. Pac last week. It was non-working, and apparently was not turned on for quite some time. She is disturbingly clean on the inside and out, and only 6018 credits on the counter, though.
Since I've gotten it, I've gone over the usual. Resoldering questionable connections, reseating chips, checking fuses, etc. One problem I noticed was that the daughterboard ribbon cable z80 chip connector has a pin cleanly busted off of it on the last position. Removing the entire daughterboard from the equation, and after popping in a known good Z80 in that slot (from what I read was a good troubleshooting procedure) I figured I'd have the problem isolated....
However, the fast moving image photo below is what comes up now, along with a constant hum from the speakers. Before I start randomly shotgunning potential parts via Bob, I figured I'd ask people with a lot more experience with Pac setups than myself where I should be focusing my attention.
Thanks everyone
