Yes, now that I think about it my dad's company had a Model 10.
I sometimes visited with the night operator.
I think there was a Model 8 and a Model 12 also.
We should say that the full name as System 3 Model 15D.
Back in high school (Fountain Valley High School, Fountain Valley, CA,
Class of 1980), I had two years of programming on an IBM 370/135 at the
District Office. We had a dozen terminals in the room (a motley
collection including Lear ADM-1s and an ADM-3, a couple of Datamedia
Elites, as many as 3 Decwriters, a Model 43 TTY, and a portable thermal
printer that could use a built-in acoustic coupler modem), all
multiplexed on a pair of leased lines (if we were lucky, we could get
them all going at 300 Baud!). OS was McGill University MUSIC. Compilers
available were VS BASIC, FORTRAN G1, and WATFIV.
They later upgraded to a 4341 on site, still running MUSIC, but with a
whole room (the "business" lab) full of Memorex 3270 terminals.
Batch jobs had to be submitted on Hollerith cards; there was one
keypunch available.
