ADM3 and ADM3a's were used in all sorts of installatins because they
were CHEAP. My first use of one was a "big" Nova system.

(Amusing anecdote: we had all ADM3's (upper-case only), did all our
editing in NSPEED, DG's version of teco. One day we got a software
upgrade or something, had to edit files that came with, and couldn't!
nspeed commands basically stopped working... took many hours to figure
out that the files contained lower case characters and of course all of
our nspeed commands were issued in UPPER CASE (the adm3 displaying
abcdefghi... as ABCDEFGHI...)
