Had it on my 486/133 briefly, but I still haven't made the jump to having Linux on a PC I use all the time.

In 1987-1988 I worked briefly with an HP lunchbox computer (Integral PC) that had a UNIX installed. It was a 68000 processor box with a whole MB of RAM. About all I learned about using UNIX then was "ls -last".

Cheers,
Scott.
