Introduction: Hi, I'm somewhat newer to arcade restorations and ended up with a Pole Position 1 as my third cabinet lol. It came with the boards for Pole Position one and two with both having battery acid damage, PP1 having much worse damage, and would boot to garbage when powered. The AR boards output 13v so I fixed both the AR boards, before I powered the boards, replaced the big blue capacitors, removed the battery, fix the acid damage, and replaced the damaged components on the PP1 boards and it booted and worked from there with no issues.

Problem: The PP2 cpu board had been damaged from the high score battery so I removed it and replaced the damaged components and sockets for the chips nearby but it still boots to garbage. I checked the voltages at the test points and it was fine reading 5.01v and I have spare working 7C and 7E chips that I thought could be the problem, as the PP1 board I had needed new ones, I swapped it but still no dice. And now I'm not sure what to do from here. Any advice helps!
