When I was working at IBM Bermuda (as sort of an intern), they used a 360/20
as their main service bureau machine. (I'm pretty sure it was a /20, and not a
/30.) It had a card reader/punch, 4 (IIRC) tape drives, and a 1403 printer.


The /20 was very limited, and not a general purpose 360. There was also the 360/22 and 360/25 that were variants of the /30 model. One was cheaper, one was a little faster. But, if they were doing mostly RPG work, then a /20 could do that.
