Working on a Berzerk, that gets 8 beeps but won't run.
Manual states could be a closed switch that shouldn't be closed, so I set switch 9, and did the on screen diags. All switches show open except 9 of course.
The BSC-1000 is known good. Well everything except this particular ZPU I'm working on is known good.
So it's not a monitor that works.
Getting no lines etc when doing the switch test.
No Rolling or sync issues during switch test
Won't coin, won't play, won't run with free play romset either.
