Hey Bill,
Hmmmm, it actually sounds like the exact same symptom I had from the
Space Wars sit-at that I fixed a while back. Zonn was probably pointing
you in the right direction with the 7406. It's been too long for me to
remember the details off the top of my head, but basically there is a
"voltage watchdog" that blanks the beam (mostly) if one of the voltages
isn't present (something like that anyway). I had some inexplicable
problem in that circuit, so I just lifted the pin on the 7406 and it
started working. I figure if it lost one of the voltage supply rails in
the first place I'd notice it...
