With all the talk about PETs lately, I've been keeping an eye out for one. I managed to pick up a non-runner last night for a pretty tidy price, from a collector who was having a clear-out. It has a 2001 case and 9" screen, but the main board appears to be from a 3/4000 series machine with a full complement of RAM.
It doesn't do much just yet, though. It has the common "garbage screen" when switched on, but only for a second or so, then... total darkness. Reseating everything that's socketed didn't help any, so I whipped the board out for closer inspection. There were some pretty gruesome-looking repairs on the back which I'd like to fix properly before continuing the diagnosis. Looks like someone had set to with a pretty beefy soldering iron and half a bucket full of flux! Most of that is cleaned up now and I'm making a start on repairing some cut and lifted (or even completely absent!) PCB traces.
Should at least keep me busy for a while ;-) I've whipped up a quick web page with some pictures, on which I'll be documenting my progress.
