As long as we're on the business of firsts, what was the first operating
system to refer to mass storage devices by single letters, starting with
"A"? Does CP/M have this distinction? ISIS, IIRC used F0: and F1: for the
floppies. Think of all of the keystrokes saved! Cheers, Chuck
The first one I encountered was the MSOS (Mass Storage Operating System)
software on early Control Data 3200 systems. MSOS and MASTER were both in
the field in the late 60's. I was trained on MSOS in 1966.
A lot of ideas in CP/M and similar progenitors came from systems already in
the field for years at the time of the early micros.
