Acramatic 850 "CRT LOGIC" error
Have a lathe with Acramatic 850 and color CRT which suddenly started failing self test. Stops with flashing CRT LOGIC fault.
Curiously, if I unplug the "GRAP" graphics memory card ribbon cable, it still gives this same fault. I would expect that to cause the CRT RAM TEST fault (earlier in the self test list), but it doesn't. Perhaps that is testing other CRT RAM...?
I reseated all ROMs, PALs, connectors, and cleaned the board. No progress.
Suggestions appreciated. BTW, Tom H cannot recall ever seeing this particular fault.
