A couple of months ago I traded somebody here (don't recall who, sorry guy) a working 2-port 5200 for a dead 4-port. I wanted the challenge, and had never had a 4-port before.

Well, it took a while, and a bit of work, as well as a terrific education from the generous folks at sci.electronics.repair, but as of about 11:15pm tonight, the 4-port works again!!!!! WooHoo!! I replaced a couple of MJE-210 transistors, and a 4013IC, and the system powers up again. Unfortunately, the top-half of the plastic button under the case's power button is missing, so the system can't be turned on using the power button on the case. If anybody has a hopelessly broken 5200 (2-port or 4-port) that they could just remove the power switch and send it to me, I'd be grateful, and naturally I'd cover postage. I could even give you a common or two if you wanted.


Have a good weekend everybody!
