Um, Thanks for the offer to help, but now I feel stewpeed!
I had the connectors upside down. That what happens when you have to use multiple connectors and have no key installed!
Now the problem is that the game isn't allowing credits. It's acting as though the little red reset button in pressed (roulette wheel spins on occasion) stepping the button, does step through the test modes.
I hope I didn't fry anything.....Stay tuned!
PANIC ELEVIATED!
Apparently Dave set all the dip switches to zero and wiped out the memory, so I just needed to install the board as new, all is good again. PHEW.
Lesson learned.
Once again, Incredible service from Dave at Alltek. He spent a lot of phone time helping me troubleshoot the MPU and was always very responsive to texts and messages left with his service. It's rare to get that kind of attention, turn around time and support on a product that's probably over 5 years old. I'm assuming that the header pins were corroded as a result of the the original J4 female connector pins being corroded, through no fault of his product. He still repaired the MPU for free, except for shipping costs. II would highly recommend purchasing any of his high quality products.
