i've ordered a jpac and arcadevga and they're on their way.
The coin door in my jamma cab is a Coin Controls one and there's nothing visible on the coin mech which indicates 5 volts.  12volts is indicated and presumably this is the power it requires to operate.  Ultimarc say on their web site that most arcade cab psu's won't even power on without a game board installed.  I'm concerned that my coin door isn't going to function correctly with the jpac installed.
Can anyone verify this?
