Quoted from Kennebunk:

Does anyone have a current link to the power supply you are using. Can't seem to find the $15 variety. Found this one at mouser for $42.

How do you wire an external power supply into a game? Do you spice in to the 120v and then create a connector coming out to supply 12 volts? Please advise.

So I think I get it . You attach a wire to the white and then a wire to the black after the power switch . Those wires then get attached to LN (ac) on power supply. Do you run a separate ground to the connecctor to the right of LN that has the ground symbol? V2 is 12 volts out on this unit.

Quoted from wayout440:

You don't have to, but it's a good idea. Run wire from ground symbol to ground braid on your machine. That will make the case of the power supply safer if something should short AC to it's chassis.

Ok thanks Wayou!!!! Going to try this on a GNR for a color DMD. I checked schematic and it has a bill collector same as maverick
So I might just use that for 120 volt power to the power supply.

Quoted from Bendit:

+1 especially if the molex converter is included (so you don't have to splice anything).

Me too. That would be a nice ready to go kit.
