Sound like a 650 to me and you probably used fortran.

A Z-80? Wow, 15 years ago that was already obsolete, given that Windows
3 and OS/2 were already running on 486's by then. What are you, a
technophobe??


Yes. On thinking about it it was the early 80s. Remember the Timex Sinclair
and the Tandy TRS-80?


Let's see, 40 years ago - the IBM 1620 was over the hill, the 1401 was
commonly used but hardly "state of the art." The 7090 was bigger than a
desk, as was the CDC 6600. Maybe the 360, though you would have had to
be special to see one in 1965. I'll guess one of the early Digital's,
like the PDP 7 or 8.


Don't remember what it was. 1620 sounds vaguely familiar. It was a
"scientific" computer, and we programmed it to do mortality tables for an
insurance company. I do remember that is was in a carefully temperature
controlled space, and the way we programmed it was to hand sheets with the
instructions to a punchcard operator who punched the cards and had them fed
into the machine overnight so we got a printout of the results in the
morning. Time was far too expensive to let the programmers anywhere near the
machine itself.
