So, I recently acquired 4 old computers and one of them has the legendary AMD K5-PR166 CPU. I wanted to remove the CPU to clean it a bit and I noticed that several (4 by my count) of the pins are completely missing. The previous owner hasn't started any of the computers in over 10 years. What can be done to remedy this problem? I suppose I could take it to a Jeweler and let him/her solder gold wire onto it or I can buy some gold wire and drop it into the socket manually. What else can be done? I've attached some photos that I've taken with my iPhone:

I found this guide. Could this perhaps be worth a try?

I haven't tried it personally but I've known a few people that were good enough with a soldering iron to simply solder the pins back on.

Well, what if the pins are literally missing?

You swipe some off a less desirable CPU or some other pinned IC chip or part.
Just make sure the diameter is right.

If you have a dead cpu with same length pins as the K5 to sacrifice you can cut/break the pins off at the base and use a pair of tweezers to place them in the corresponding holes the missing pins would go in. Worked for me on a K5 and an Athlon 64x2 as well
