It is likely that I solved this thing by finding an AC device that matches these values, I just need to cut the wires and attach the old 2-pin-plug to it, isolate it, and hope it works.Second is more tricky, a Fidelity Chess Challenger Sensory Champion (1982). It wants to be feeded with 8.5V (9V) AC and 1500mA. such a device I am seaaching for on the web, ebay, chess computer sites. So far in vain.Will try if the first power unit also works for the Champion, despite the lesser Amperes. I also did not manage to get positive replies from electronic stores if their are adapaters for thes terriubly old connectors. The computers have fixed wires ending in two-pin-connectors, 1mm thick, 4 mm separate, however, the CC Voice has not two poins, but one pin is replaced by one small "square". These plugs I haven'T seen since went to school, and younger salesmen in the electronics sections of warehouses even do not know what I am talking of. Collecting old chess computers is nice - as long as nothing brakes down... |
Hmm. I think I just threw away a Fidelity Chess Challenger from 1982 - comes in a golden brown box with yellowish beige and brown squares for the chess board, and the red LED display to call out moves. Had 2 of them - both had issues when they got hot to the point where the computer screwed up and forgot where its own peices were. All of them had this issue.

PS. You best bet is a DC to AC car adapter. Only problem is, those things are bulky.
PPS. Play your game fast because the heat problem will screw you up.
