I'll have a Blast City cab on the way soon-ish, so I figured I'd go ahead and get some of my research out of the way.
So from what I can tell the Blast City PSU doesn't have -5V output (or if it does, it doesn't seem to be wired up). Is there a way to add this? I know I'd have to wire a couple of additional pins to the JAMMA harness, but is there some PCB or something I can use to take 5V or 12V from the PSU and output -5V?
I assume there's some small buck converter that outputs -5V, but I have no idea what kind of wattage/amperage you need on -5V for arcade PCBs that use it. I think the only PCB I have right now that needs it is Double Dragon.
