I don't know what chain we used at University of
Mo, Rolla. We had a
360/50 with 512K of memory and a 1mb LCS so could run a lot of stuff.
they had Fortran H as well as the other compiler languages, would
assume they had that chain. I don't recall any changes of chains
other than perhaps failures.
The fun story I have was from when I was playing one night and had
accidentally done a skip to channel, 12, which on our printer had no
stops, so it would jet paper out as fast as it could go.
The first run of it jammed a big mess in the back output feed. The
operator guy, Dennis Ditch asked me after he had cleaned up the mess
if there were any other runs queued, and I thought there weren't. He
had the back up, (mentioned in other posts could mess up your time if
you had something sitting on the case.
Anyway people may recall that there was a set of controls on the back
by the takeup, and he was sitting there when he asked me about the
other runs. The system was MVT and was running jobs w/o anyone
attending the console of course.
He went ahead and put it back online. The thing that impressed me was
that the paper flew over his head and didn't touch the floor for 20'.
Oops, guess it was still queue. He hit the offline very quickly, but
probably 30 or 40 pages were ejected, luckily not jamming the printer
again.
He left if offline and went over and killed that job, and checked that
there weren't any others.
thanks

The carriage control tapes had the sprocket holes dead center which lead
to people putting them on backwards by accident and since most people
only used a couple channels for any given form, this would lead to paper
runaways, as would neglecting to lower the brush block after mounting
the carriage control tape.
I once saw one of the large system CEs repairing a print train that the
customer had neglected to fill the oiler and the train seized. The
filling the oiler was the customer's responsibility so the repair of the
train was billable. The type slugs I saw where not coupled together and
had helical gear teeth on the bottom that coupled with a gear in the
train that was driven by the motor. I am not sure what model of 1403
this came from but it was one of the models that had covers that went
all the way to the floor. The print trains had a separate machine type
and I seem to recall that the customer was obliged to purchase them even
if the 1403 was leased. The 3203 printer used the same print trains as
1403.
