Calcomp (and others?) had automated tape libraries for reel to reel taps.
STC (and others?) had automated tape libraries for the 3480 carts
plotters?
1404 printer (I've mentioned before) that could print on two tab cards at a time
forget who, but an archiving system using 14 inch (?) video disk platters. 7(?) years of
all customer statements were stored on these.
3rd party extensions for main memory (took a 360/30 to 96 KB or more, beyond IBM's 64
KB limit)
The cartridge tape library that staged onto 3350s (and later 3380s?)
Of course there were 7 track tape drives for compatibility with prior systems. When we
were down to only one job a week using the 7 track tape, we discovered the client we got
tapes from had only one 7 track tape, just to send us tapes.
--going beyond mass storage
the 2956 check sorter (rpq) that was two complete 1419 sorters connected head to tail to
give twice as many pockets (it had a second read unit, don't think it actually read a
second time).
the 3890 replacement for the 2956 that was built in modules of 6(?) pockets you choose how
many up to 36 (?)
3270 terminals that were only 12 lines of 40 characters
my favorite terminal 3190 that was neon gas, so monochrome, but could take 5 addresses,
and flip between 62 lines of 160 characters (always there), to 4 terminals of 62x80 any
two visible at a time, or 4 terminals of 31x160 characters, any 2 visible at a time, or 4
terminals of 31x80 all visible at once. when given a choice, my new boss was surprised
that I chose that instead of the color 3279 with graphics that everybody else wanted.
Great for running virtual systems...
