Ow. I was looking for something a lot earlier than that. I used RSTS-11 in
the '72-'74 timeframe, so it's a version from that era I'd like to have. Any
idea what version that would be - and if it's still extant?

When was that one?

OK, better than nothing.

Hmm. I guess technically HP owns it now?
Not so sure of that. When Mentec went away the word was that some other
party had bought all of the old PDP-11 OSes (except maybe IAS) but I have
heard nothing about it in several years and fear a lot of it may now have
become lost. It certainly isn't being held in secret because of some percieved
RSTS was my favorite PDP-11 OS and I have long wanted to see it Open
Sourced in its demise as I always wanted to try porting it to other machines
just for the fun of it.
