Debugging coast to coast got us really close.
#Major havoc control full
Popped a couple good ones in and we had full color. They were getting data in but just outputting 1’s. Once I got the board on the bench – it didn’t take too long to determine that the 12K was the issue. It’s a great weekend morning with coffee activity. the board found it’s way to me.īuilt a Major Havoc adapter for my test rig. After a number of coast to coast debugging sessions. Once we got to the PCB, we determined that all 3 colors were locked on vs. Because the entire cab was being assembled from untested/new components – it took a while to determine the monitor was good, power was good, etc. Pretty much everything came out all white. Next he connected to the repro harness and connected the X/Y to a scope and the game was running. Poked around with a logic probe and it seemed to be running (no resets on the CPU’s). Once all the bits and rare components were finally installed – we slowly brought it up on a bench supply and made sure it wasn’t pulling too much current. My buddy on the west coast did a really nice job collecting all the parts and assembling this board. It’s been a long time in the making but there was a hiccup on the PCB. He decided to get the reproduction cabinet and build the reproduction Major Havoc PCB. A good friend always wanted one – but an original is pretty hard to come by. But I’ve been pretty lucky with this sort of thing. I never really expected to work on a Major Havoc set.
