Pong Help!

I just bought a Pong system from Goodwill and I need to know what kind of power chords that we need. Can anyone help me? It's a Quadtronics Model Number Q-376. Anyone know some really old school info?

Damn, Pong system without a power adapter? Wish I could help, but I've never played a system older than my NES.

I also wish that I could help.  Maybe you could try asking it on Yahoo Answers or something.
