Well, I remember the /50 at Rolla, they ran very little
locally while I was there, mostly used it as an RJE terminal.
Cards and 1402 printer. So, the 1050 was not real busy.
The /65 at Wash U was very heavily used, and souped up to
the 9's. It had dual internal memories (as opposed to the
horrible predecessor, a model 50 with LCS, which made it run
slower than a /40). With the dual identical memory units,
you could use interleaving. Anyway, they had 2 Memorex 3764
DASD controllers, first with Calcomp 3330 emulators, and
then with Memorex 3350 substitutes. They got Memorex to
hack up a version of MP65 so that they could take advantage
of RPS. They also had a bank of Hitachi 200 IPS tape
drives. And, so, the 1050 was just chattering away almost
constantly from about 7 AM to 7 PM. I think they finally
got a CRT for the tape operator. But, they kept the 1050 as
main console for the hardcopy record.

That's one area where CRTs are sooo much
better. The
S/360 machines
just pounded the hell out of the SYSLOG device. I guess
the Selectrics
were better than the Model B-based console typewriters,
which always
seemed as if they were going to fly apart.
As a typewriter, the Selectric is pretty good. I still
have a
correcting Selectri III with a broken drive belt (I have
a new belt
waiting to be installed), but I haven't gotten up the
courage to repair
it myself yet--it's not a simple job.

IBM called up the local guy for our area when the
University bought the 360/50 and told him to report for
training. They delivered a /40 for a year because of
problems with making the 50 work.
He was the regional IBM Selectric repair guy. The 1050 on
our systems always ran fine. As did all the Selectrics
around the area. He still had those support calls.
