Tried that, with these old proms I always scrape the
black stuff off the legs with a razor blade and re-seat.
I even replaced one socket.
I took the roms off the board and put them in my
Asteroids and they boot just fine.
I did try a suggestion from Chris, checking the NMI.
What I found in the test mode, NMI is high and in game
play it is pulsing...when I disable the watchdog the pulsing
increases quite a bit.
I'll just keep pluggin away...
