Hey all,
I picked up a Quadrapong machine at the Pinball at the Zoo show today. I'm trying to diagnose the problem it's having and I'm not 100% certain if it's the board or monitor. Basically I've got an image that isn't stable vertically and usually it will need tweaking horiztonally when first fired up. You can make out the game playing a little, but that's about it. My gut feeling is the Zenith 19EB12 b&w tv has issues but of course I want to make sure. Has anyone tried using another TV to test the output from those early Atari Pong games? I can probably easily find one to use for testing and that would rule out the original Zenith TV as the culprit.
