Why JAMMA?

krick:
You could put a big resistor from each of the pins to ground.
It would get really hot.

SirPoonga:
I wonder if there is a way to use a relay or something to auto shut the power supply off.

Do you mean when there is a PC video signal on the J-PAC, the cabinet power supply is switched off with a relay?  I sure this can be done.   However it seems like a lot of work and I'm not totally sure what exact problem is being solved.

RayB:
The problem is that an arcade Power supply will "burn up" if there is no load on it for an extended period of time. That was my primary concern. But if the multi-jamma is still powering whatever other PCB is plugged in there, well then that takes care of that.

The only remaining issue is cost.  ;D

paigeoliver:
Hmmm. I have a solution.

Buy a non-working board on ebay, take your pick, one that boots up to garbage will be best.

Wire it up to the power supply as well to provide the load you need. Problem solved.
