Well they were doing mice in 1982 along with some gui editor. I think
modula-2 and debuging came in 1983. Selling mice by themselves seem to
have been a couple of years later, whenever the C7 came out, although
they were selling mice to Apollo and HP before that. Not sure if they
also supplied Sun or if that was someone else, although given it was
optical, probably someone else.

Yeah lots of options today.
Borland and Watcom and such all seem to have died out by now.
