Hi all,
Been pulling my hair out on this Tempest for months. First it would play blind, then found the 15/-15v regulators bad on the video section. I replaced the 2 regulators, the pots, and electrolytic capacitors.
Now I have a nice image, that is flashing free play on screen, but now the start buttons are not flashing, and can't start a game. I put it in diagnostics, and do not seem to get any reaction when pressing either player start buttons, zap,or fire. On one test screen there are letters/numbers in lower right that count up if I turn spinner slowly. I tried replacing the POKEY that is associated with buttons, but did not change any thing.
Any ideas on what to try next
Thanks for any help
Aaron
