Hello everyone,
After getting my minigun supergun, I had hooked up an atx psu to the minigun's molex connector without realizing that the pins were different (So I effectively ran 12v down the 5v rail and shorted 12v to gnd). That caused the psu to activate the overcurrent protection and just shutdown immediately after I turned it on. It wasn't until closer imspection was when I noticed that the pinouts were different and I rewired it. I now have video but it seems to have a click of death (more closer to 8hz) and garbled graphics.
I was really hoping that split second of 12v on all the rails didn't kill it but I guess it did. Switching BIOS's doesn't help and it still does this without any bios installed.
I've tried probing around with a logic probe and the m68k's clock is tied low and the Ym2610 gets unusually warm. Is there any recovery from this? I just hope it didn't take my KOF 99 cart with it
