- If you get the V1 that
ran on an -11/20 (which is mostly compatible with
the /04 and /05), it should run on an /04. (Not sure what
you'd use for mass
storage, on a physical /04, though.) I'm not sure when they
dropped the /20 -
I think V4 n(at the latest)? But V2 and V3 are lost.
Yes, the reconstructed 1st edition may run (though from
dates and such, it's somewhere between 1st and 2nd edition),
though I've no direct experience with 11/04 hardware, nor
ideas on how to bootstrap it onto appropriate physical
media...
I have it in my head that the 4th edition was rewritten
for the 11/45 and removed support for 11/20. I thought I
knew why, but could only find part of the story in the
manuals...
There's a strong note in the 4th edition preface that it
applies only to the 'c' version of Unix and the 3rd edition
preface has a note saying the manual doesn't apply to the
11/20 version and to look in the 2nd or even 1st edition
manuals for that.
As others have mentioned, Mini-unix and/or LSX might have
a shot, but it might be best characterized as a long shot.
