It ran OS/360 (no /360 or /370 ever ran UNIX, AFAICR); later on /360s
started to run MFT and MVT; from this point on we started the road to
the current zOS/MVS and OS/VS1 (which, I think, were still used a few
years ago). It is said that at the core of zOS you can still see an
emulator for the earlier IBM machines (I do not even remember their
code anymore, 703?). And yes, usually you would have a (very) few
hundred KBytes of main memory -- between 100 and 300K). And these were
the systems we called 'mainframes' at the time, requiring massive power
and cooling and quite some racks.

Fortran and Cobol come from the 1950s-early 60s.

But, anyway, there was no machine with 16MBytes of main memory in the
60s -- and if it did exist, it would have costed a quite some million
dollars, just for the memory.
