The S/360 is still mostly around. These days in the form of IBM z Series. In 2007, I was
working as an admin on a couple z900s running z/OS. That was my first exposure to a system
that didn't have a hierarchical filesystem. I learned JCL and REXX. I'm still
quite fond of RACF, wish more systems had something like it.
It's unfortunate that the system is so hard to get your hands on. I'd like to keep
up on it, but having a job where you admin it is nearly the one way to get access.

Back to FORTRAN. At one time utilities for new
hardware (1970's) was written in FORTRAN to
portable. Any idea what machines they expected the programs to be ran on?
When the 68000 (68-thousand) first came out, Moto provided a simulator (written in
FORTRAN, TMK) to run on IBM 360/70 hardware (or at least that's what we ran it on,
under MTS). I believe that was quite common as the 360/70 arch. was so prevalent,
particularly amongst time-sharing services and computing centres.
