Sorry. I meant the 3b1 (aka Unix PC)
I think it was a logitech two button rectangular wedge shaped mouse
used by lots of vendors. They came in both serial and parallel, I
think the AT&T one was serial. It has been a long time. Both had a D 9
pin connector.
A picture search on google "3b1" brought up a poor picture of the
mouse with one. Hard to see what it actuually is.
I had several 3B1s go through my hands in the early 1990s.
