[way2cool]

Hi, ive posted before about this old pong type system, so here it is and What im needing is what kind of power supply do I need to get this running. Theyve got so many differnt voltages 6v,9v and I dont want to short something out not sure if it even works. So if youve got one and can give me any info on what I might need or something missing. please help. Oh yes its made 1978 Ideal.
What I have is the console and the 2 guns that came with it. thanks

Some pictures would be nice, since usually the PS voltage and polarity are indicated on the device someplace.
