Hey Chris - I see your advice all over System 80 questions on here -- thanks a lot. While I have you do you have a source for the edge connector pins?

My Black Hole works perfectly now... with the exception of the sound. It's sometimes works fine, other times plays all the wrong effects at the wrong times, and sometimes locks on a hellish scream in the middle of a game, and I have to restart the machine to fix.

I have read over and over about connectors on System 80 causing such intermittent problems, so I was thinking of repinning A6-J1 (pictured).

Thanks man.

I see - thanks to you both. I wasn't understanding that the whole connector should be replaced. It's out of stock at Great Plains - Molex seems to have discontinued that model number and replaced it with another with the ribs in the wrong place. But it looks like Marco still has them!

Ok, interesting... the current connector and the pins inside (weirdly crimped perpendicular to the connector) look nothing like the new pins/connectors so I assumed I should replace both at once.

Awesome. I think I can make that happen. I don't know what I'll do with all these extra connectors I ordered! Thanks once again.

The new 12-pin edge connectors I received from Marco were in fact the Molex "replacement" part for the original part #09-01-6121, which has one rib in the wrong place. I carved the misplaced rib out with a sharp utility knife and then repinned it, wire by wire, from the old connector.

It has only been 24 hours, but the wacky intermittent sound problems I was having seem to be gone. Time will tell -- thanks... once again!
