I just bought some 30pin SIMMs to rehab an old computer. That market is fine.

I have a bag of SIMMs that I saved, no idea why, because I clearly wrote BAD on the mylar bag.

At time time I was messing around with the "badram" patch for Linux.

It's a lot harder to source ram with known errors than it is to get clean stuff, cause most of the stuff with known errors will be tossed. Makes sense to save it.
