Well, Fortran goes back to 1956, but yes the others were pretty
popular for a while after that. Sometimes for pre/post processing
for computers. Some computers would write the output onto tape,
which was later put through a tape to print machine.

The last one I saw said more computing power in a singing
greeting card than all the computers in 1950.

Some books were printed directly from the output.

I thought it was 2 megabytes maximum for the 360/91, and that was
750ns core, 16 way interleaved to come close to the processor speed.
(I believe 60ns clock.)
Even more, consider disk space. In 1970, before the 3330, the usual
disk was the 29MB 2314, of which they might have about 10 for user
files for the whole place. The 100MB 3330 around 1972 or so increased
that a little.
