Yeah, will need clarification on that jumper. Maybe someone else here can chime in on that?
As for the 5v. I have the 5v bypass cable coming from Pinball Life.
http://www.pinballlife.com/index.php?p=product&id=1545This harness update kit includes a cable with connector and installation instructions (Sega service bulletin #106, not shown in picture) for all large dot matrix display Sega pinball machines.
This harness fixes the reset/blankout issues older 192x64 displays can experience.
Simple installation takes under 15 minutes and requires no soldering.
