DumbAss System 9 MPU would make a good follow up to your System 11 MPU.

@dumbass, I wanted to throw in to see about some Data East Jurassic Park interest. My project is missing these 2 T-Rex motor boards and I would love to make it complete.

@dumbass, thank you for your responses. I didn't realize Big Daddy already had one. Looks like some time saved toward assembling another bad ass system 11 MPU board of yours.
@toddsvec, thank you for letting us know.
Can someone start a new thread for the relay boards now it is off topic from these badass dumbass boards? Thank you.

Quoted from ibis:Finally booted my WPC95 board up in a Flintstones. I got feature lamps but nothing else. The DMD is a bit garbled but I can read that is says 'U22 ERROR'. Any thoughts on where I went wrong?
Well, Flintstones is a WPC-S game, not WPC-95.

Quoted from Crash:Speaking of modern components, do you know if the EZ-something 5v switching regulators draw less power on the 9v AC pins of the WPC power board secondary connector? I think those are discontinued but I bought a few of them ahead of time. I currently have a game with a factory LM323K and soldered in secondary wire harness and would like to fix that header/connector correctly without the 9v pins overheating again.
Not obsolete.

Repin and rehead J101 and enjoy. Every 9VAC connector I see looks to be caused by loose pin connections. Loose pins generate heat due to a bad connection. Loose pins are normally caused by excessive connect/disconnect lifetime cycles, which is not an unlimited number of times before the pins start losing their tension against the header pins
I had repinned 3 J101 connectors in my games well over 8 years ago and still look new just as I had repinned them.

Quoted from DumbAss:ordered some 80SQ045N Schottky diodes from Mouser.
Mouser and Digikey both are showing these are now obsolete and end of their life cycle. Time for a substitute.
