  I'd read in one of the trade rags about the
AT&T 3B5 and thought it 
 would make a great development machine. ...
...
  Did anyone on this list ever succeed in acquiring one
around that 
 time? If so, how was the service and performance? 
AT&T carpet bombed Georgia Tech with 3B stuff around the time I got there 
(1985).  There were at least 2 3B20s (rebadged control processor for a 5ESS) 
brutally overloaded with freshmen writing Pascal programs, lots of 3B2 + 
AT&T 5620s and as I recall at least one 3B5.  Compared to the Sun gear I got 
to use at the time (3/160 & 3/50), they were slooooow, but built to last.  
Seriously physically over-engineered.
