The ISC 8001 19" got lots of service in industrial control rooms.  Several companies
rebadged it (USDATA, Dynapro, Allen Bradley).  With character graphics and a special ISA
character set it did extremely well in fast screen updates and animation.  (Think valves
and pipes turning red/green, tanks filling up, etc.)  Impressive for a 2MHz 8080.

 Only a tiny fraction of the PDP-11s, VT100s, etc. survived.  The vast
 majority were scrapped.
 While there may have been a lot of ISC terminals made, for some value of
 "lot", the number obviously was orders of magnitude fewer than VT100s.
