Spot killer on. Not playing blind. Test switch does nothing (no beeps).
If it has a bad AVG chip, it should still run, right?
Already tried swapping in another ARII with no change. +5.08 at the ROMs. Swapped in a known-good 6502 and rotated a known good pokey through both spots (unless both are bad) without a change.
I guess the next step is to verify the ROMs? Don't have access to another Gravitar or Space Duel to check it in.
The monitor had been rebuilt a year or so ago, and I didn't see any issues, but it should still play blind even if the monitor had failed.
Any ideas?
