Funny Story: Around 1990, I worked for a small computer manufacturer doing computer assembly. I remember putting together a brand new (at the time) 486-50, the fastest x86 yet. There were very high hopes for it's performance. These motherboards had the same kind of oscillator, and it was socketed so you can change cpu speeds. I installed the oscillator and the CPU, and powered the machine on.... Nothing happened. If you put the OSC in backwards, it tends to get really hot! I knew this, but I had always in the past been careful, so I never experienced it. I was pondering why the PC wouldn't post, and I thought I would check the temperature of the OSC, so I slapped my thumb on it. YEEOOW! That sucker was searing! I pulled my thumb away, shook it, swore, and looked at it. On my thumb was printed 000.05 - My 50 Mhz red badge of stupidity. Important lesson.
