Archived from groups: rec>games>video>arcade (more info?)

Hey, im trying to connect a MultiJAMMA and in the manual it says I need
to connect an extra power supply to the switchboards. So I tried to use
a 250w computer power supply. I connected the power plug that is for
cdroms/harddrives into the JAMMA switchboard, and another plug to the
MultiJAMMA controller. But when I turn the cabinet on, the second power
supply doesnt turn on. What can I do? Thanks for the help.

jump the green wire in the big plug that plugs into the pc to a black
ground wire that is in the same plug.
