I got a pinball machine that's made in the Netherlands by Jack van Ham , royal escape.
In this machine they used a jpm sru 9980 board.
This pinball machine will not start-up, all voltages are present.
the questions are,
Will it boot without a backup battery?
What kind of battery is it, voltage?
And is there a way to manually reset this board.
Hope someone could help me out, greets Ramon
