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.
