Hi! I normally avoid saying things like this... I have a bunch of IIc compatibles (Laser 128) that take the same power adapter as the IIc. The connector is identical. The adaptor is a 17V unit, very boring and average. Because I only have one original supply, but about 8 machines, I ran several of the others off a 13.8V automotive power supply via a suitable cable and they ran perfectly. The rough DC is regulated internally, so the machine doesn't seem to care much what it gets so long as it's not too far off 17V. WARNINGS... This is a Laser 128. It seems to be practically identical to a IIc in most ways. However, I can't say whether an original IIc would be happy running off 13.8V as the Lasers were. I do know that their power supply was a very simple single-voltage DC affair, and the 7-pin DIN connector was just a weird choice. As to which pins do what, you can tell by popping the machine open and looking, or looking it up on the web... http://www.xs4all.nl/~rimmer/files/schemas.txt This states the PS voltage is 15V, that may well be correct for the IIc. Also note that if you accidentally reverse the connections on the PS connector, it will reverse the voltage across the IIc, and quite possibly destroy it. If you're not 100% confident that you're going to do the right thing, it might be better to try to find a IIc (or maybe Laser 128) power supply...

It's the male side of a 7 pin plug. Thanks. TRS(trash)-80 in the next coupla days... oh boy, oh boy!!!!!!!!!!!!! I love getting "new" toys.
