Years ago, I got a really messed-up interposer. It was pretty obvious that it was probably a sweet upgrade, but I didn't really look into it because it looked like a hopeless case. However, when I did some research for the IBM Model 57slc restoration, I found that this is the matching 386 to 486 upgrade! Needless to say, I had a go at repairing it despite the horrible state it was in.
