Atari QuadraPong Help Needed

[Lee Krueger]

I have a QuadraPong with a cabinet that is in excellent shape. The unit doessn't work. I check ed the power supply and such, it all seems to be ok. Now I need to dive into the nuts and bolts of the main board. Can anyone here provide me with the schematics? I found this site wich list some Technical Manuals (also noted).

http://www.atarigames.com/manuals.txt
TM-012 QUADRAPONG, Operation and Maintenance
TM-034 QUADRAPONG, PCB Service Manual

If anyone can provide a copy of these, I'd be very much in your debt. I'd love to get this museum piece up and running again.

Regards,

I haven't seen those manuals anywhere, although I haven't looked that hard. But first, you said the power supply seems to be fine... did you check the voltages at the chips and stuff? IIRC all of the voltages are AC to the PCB and the PCB does the rectifying. I took a quick look at the one at CGE, and I remember the +5V line was only reading about 4.3V. So the logic probably wouldn't be working correctly. I'm guessing the connectors were bad, since it was pretty dirty inside, and maybe something in the rectifier circuit needed replaced.

I don't know much about B/W monitors, but you should narrow down what actually works and what doesn't, and checking for neck glow can tell you whether the monitor might actually work if the logic is working. I assume you don't get any sound either (not playing blind)?

I'll ask on another arcade forum about the Quadrapong manuals though and let you know if I find anything.
