Do arcade boards (jamma) get their voltage from the harness? Or do you have to hook up each board varying by the voltages needed for each one?
my MVS and ST-V run fine with the +5V and +12V lines on the harness... there is also -5 and -12 but few boards use them.
The voltage should almost always go through the JAMMA harness in an arcade machine... certainly with JAMMA standard boards. -5V is only used occasionally - I think that technically you can do without it on MVS. Don't forget the minimum current draw on each rail, though!
I just bought a supergun , and need to know about voltages now, like naomi, it has a seperate beefier psu I think.
Err, well wiring Naomi to JAMMA isn't exactly as easy as some harnesses. You need the Sega board and a PSU... Oh, or you could go with the Capcom thing. Check it out here. *Edit* Sorry I shouldn't say that, it may confuse. Naomi NEEDS a JAMMA cabinet (or Supergun). However, you're supposed to use Sega's PSU (disconnect the original entirely) and Sega's Coin Acceptor. That's the official way of doing it. I believe Capcom's way uses the PSU of the actual cab. It just depends how complete a Naomi setup you have. Personally, I'd rather have a Naomi cabinet for Naomi playing - then I'd know I had everything straight away.
