How to wire test and service only from a jamma harness?
I have the need for a test pattern so I can align a tube swap I did today. I don't need anything else but that test pattern.
I have a mk1 or mk2 board sitting here running straight off a jamma harness. No controls no nothing.
I have two small momentary push buttons. How would I wire this to access that test pattern?
14 Service to?
15 Partside to?
Would it be ground for both tied together?
