The main target for the PDT-11 was RT-11.   It was slow.   The floppies
spent a great deal of time seeking.

Slow, but still a PDP-11!   I had a /150 (plus VT62 and LA36) as my main
computer when I was a frosh at RPI ('84-'85) and it was quite a bit above
average compared to other personal computers at the time (C64, Apple ][,
TRS-80, Atari 800, but IBM PCs were still rare -- so mostly fun toys with
pretty graphics but slow and no disk space and usually no 80-column text).

With 60 KB and most of the floppy/TU58 driver up in ROM space its free
memory was at the very high end of MMU-less PDP-11s -- stuff fits in a PDT
that won't run on a "real" LSI-11.

I ran a PDP-8 at home back then. Boy, those RK05 were fast, and stored a lot. :-)
Also, PAL8 was ridiculously fast... MACREL was a bit worse... But still, compared to what most people played with...
