This is one of those things I would normally use my CAT Box on... But that thing decided it no longer wanted to cooperate.

I've been looking at a couple Tempest PCBs I have lying around. One of them I've got ALMOST working... But it resets when in game mode.


It's fine in test mode and audit mode. If I can get it to go to attract, it'll go through the whole attract sequence, but doesn't like the actual gameplay section.
I noticed that in the MCMLXXX Atari copyright message, at times it's prepended with a "B" between the copyright symbol and the M. so I feel like there may be some kind of ROM error going on?

It's not a mathbox problem. This issue is the same when I swap a mathbox from a known good boardset.
