Converting -12vdc from the +12vdc of a JAMMA harness
Hey dudes, here's more proof I'm a newbie:
I've got an Exidy Spectar PCB that needs the usual +5/12 voltages along with -12vdc and I was wondering if someone can point me to a simple yet reliable circuit for converting it out of the standard +12 in a typical JAMMA switching supply? I know computer ATX supplies can provide all the needed voltages but I wanted to make an adaptor that'll plug into a jamma cab without having to change anything.
