Re: Sega G80 Test Fixture

I've seen two approaches to debugging Sega G80 boards.

1) Cut away both sides of the G80 cage. This allows you to access the
top or bottom of a given board while it is running. Unfortunately, not
both at the same time.

2) Using a junk G80 board, solder wires to the edge pins and run the wires
outside of the cage connected to a large edge connector (or two JAMMA
connectors put together). So you plug in the junk board, and then plug the
board you want to test into the external edge connector.

I have both. Of course, you need a working text fixture (g80 game) to start
with.

I've got plenty of junk g80 boards if someone else is interested in doing #2,
or if you need parts off them.
