Great video.

Machine pin sockets can be such a pain (and not worth the trouble in my opinion)

Thanks for making these videos. Pole Position is one of the more difficult games to repair.

Nice work - I picked up 3 (4?) PP sets just because they are complicated - I'm pretty sure they are similar in architecture to DigDug - just more stuff.. I haven't got them on the bench just yet.. But these videos have been motivational. I have a couple repairs ahead of messing with them. Thx

When reading a bad ROM chip I didn't know you could test the programming voltage because won't it erase the data content that is loaded on the ROM chip if you're trying to test the programming voltage?
