Well, the University of Oregon might disagree with you
about the PDP-7.
They ran the DECsys monitor,
Ah, I didn't know about that. Still, pretty sub-minimal: Fortran II,
assembler, editor, period. It made OS/8 look quite rich by comparison.
Hardly useless....
However, according to the manual, DECsys required an 8Kword PDP-7, whereas
the "Space Travel" (not "Spacewar!") machine had only 4Kwords.
And what's wrong with OS/8?
Nothing. Indeed, I cut my teeth on it on a PDP-8/M with 8K and a single
DECtape with the driver in ROM. I was using the term descriptively to
indicate the kind of OS available for the PDP-9. A modified version also
ran on the '15, it seems. But the native OSes were DOS-15 (roughly RT-11)
and RSX-15 (a classic DEC RSX).
