One problem with Suns as general time-sharing machines is relatively
slow terminal i/o.  I believe I read a Sun spec which only promised
4800 baud continuous output (9600 baud input).  I can confirm that
when my Sun is handling 4800 baud the number of interrupts shoots
through the roof.  Perhaps there are smarter boards on the way, but
where our 780 supports 80 terminals, I wouldn't want to be on a sun-3
with 8, even though its cpu is theoretically faster.

One the other hand, we routinely use Suns here with 1 or 2 terminals
in addition to the hi-res console.  This is how faculty (who mostly
have the suns) get extra terminals to their students (who mostly
don't).
