    Pheonix - Toei CM-A20 - First time trying to repair arcade

    Now that looks like horizontal sync is fine but vertical sync is not correct. Yes sync is supposed to snap-in, the monitor supports a small range that i needs to lock on to.

    Pheonix - Toei CM-A20 - First time trying to repair arcade

    You definitely have no horizontal sync there still, so you've either got a problem with the PCB or the monitor. My money is on the monitor.

    Pheonix - Toei CM-A20 - First time trying to repair arcade

    The first big knob on the left is Horizontal Hold, that's what is wrong with your image. If that knob doesn't fix it, there might be something wrong with the monitor or (less likely) something wrong with the horizontal sync generation on your board. I see it's combined sync (white wire) so it's...

    I’m going to assume this isn’t supposed to look like this. Am I screwed?

    Atari didn't put mask on the top of a lot of arcade boards. Asteroids, Centipede, Missile Command off the top of my head.

    Sega Turbo Cabaret Side Art

    Seems like this sideart is cursed. Nobody else happened to finish a vector of the art to release did they? A few people were working on it earlier in the thread.

    Pole Position - Engine/Speech OK but no other sounds make it past the multiplexer

    Hi all, I've been working on this Pole Position and almost got it back completely. For the sound, I've got the engine noise and speech working fine. The other sounds are not showing up at all, but I have evidence they are working, at least some of them. For example, if I check "CHANL2" from...

    NeoLoch Inquisitor binary files?

    Mine just died, and I had already purchased a new base to get the PIC over again a few years ago. Could burn a new PIC in seconds if I had the file!
