sure, most of it probably won't sell anyways, but still. On our local auction site you can't even block sellers so you have to scroll through heaps and heaps of overpriced hardware. I keep seeing the same items and I can't even hide them. One seller has fantastic things but his prices are so high …

well it would be nice, unfortunately even completely random CPU lots get super expensive nowadays ^^ seems like a few nice ones in there Even newer CPU lots? I'm currently aiming at the cheap (s478, s775, s939, post-2000 server CPUs) segment, these are very affordable now and people don't care …

Got these CPUs in the mail today. It's better to get them while they are dirt cheap, they don't take up space anyway.

A 386 with coin battery. The world would be a better place if other manufacturers had followed this design.

A stupid name is usually a dead giveaway.

Forget them and use more expensive but reliable brands: anything made …

I just faced a similar problem and it was the I/O controller. I have three 5,25" drives that refused to work properly. The PC recognized the drives but behaved erratically while reading disks. Sometimes it worked fine, other times it couldn't read anything at all. I cleaned them, lubricated them, …

Was it installed in the same 486? Try a different cable or connect it to the other edge connector. Try it with a (different) I/O controller.

That soldering job with all the wires tangling left and right... brrr. And what's with the strange wire colors? Red, orange and blue as GND? What about beep codes? Get a speaker. Get rid of that "PSU" and get a standard AT PSU first.

Check continuity between the 5 keyboard pins and the KB controller. Here is one of mine as example: 1. - (seemingly NC) 2. pin 5 3. pin 39 4. pin 20 5. pin 1

To be blunt it's a hot mess, sorry. Wires are too thick and disorganized, everything is covered with (burned) soldering gunk and you can't really see what's what. You just have to check continuity again to see what you have missed. Won't be easy. Use the photos you made before you started the …
