Anybody still using AT&T 3B computers?

I worked for AT&T in the 1980’s when they brought out their UNIX product line, the 3B2/5/20 series running UNIX System V. They also brought out another system called “The UNIX PC”. I was wondering if any of you old-timers ever used one of these systems and if any of them are still in use today.

Any other stories about old computer gear would also be interesting.

Thanks.
