Yes a Cyrix P166+ from 1996. Died in May 2000. System producing all kinds of GPF. Figured it was Windows 95 screwing up. Booted off another disk in DOS and it would get program execution errors trying to run FDISK and FORMAT! Hahaha. Yes the cpu was FUBAR.
I sent it to the EDM room and they cut the cover off so I could see the die. That was on my desk for the longest time and probably still is.
