But, in the earlier quote, the context was input of
bulk data into batch
processing computers, such as 360. ?The optical readers were capable of
much higher speeds, which was the limiting factor in those days of data
processing.
IBM 2501. Damn near every 360 installation had one.
It hogged a channel, as it had a built in control unit. 2520 is the
corresponding hoggy punch.
Years ago on this list was a pointer to a Government auction for a lot
of six (!) 2501s. There was also a pointer to a 2501 in Newfoundland.
I wonder if any of these machines survived.
