[comp.sys.dec] MINI-UNIX

ken@rochester.UUCP (06/17/87)

If I were you I would go buy a PC clone and put Minix up on that. Put
your PDP out to pasture as a print buffer or something.  No offence
meant, I like the architecture but a 64k address space and no memory
management on the 11/10 is rather limiting these days.

I have a Bell Labs manual from the mid-70's which describes a
"MINI-UNIX" for the early PDP-11's (it specifically mentions
the PDP-11/10).  Since I also own an 11/10, I'd be willing to
buy this software if there's the slightest chance it might still
exist somewhere on a long-neglected rk05 pack.

Aw, have a heart.  That poor little 11/10 can do just fine under rt11.  I had
an 11/04 that ran just fine until the #$!#!@@!#!# power supply bought the
farm.

I suppose I'm at fault for not mentioning my interest in MINI-UNIX is that
it would be rare and special: it's unusual to find Unix on anything
smaller than an 11/23 these days.

(I do already have a nice Sys V [mc68010] system, and RT-11 v5.1 for the PDP)

MiniUNIX was a distilled down V6 kernel.  Certain things were removed
(noticably pipes) and things had to be linked to start at 1000 to
make up for the lack of memory management.  The scheduling/swapping
was also crude as a result of this.  MINIUNIX is Bell source code,
so unless you have a source license for your 11/10 (only really cheap
if you are a university) you couldn't legally run it.

Anyway, Art Hays, now at the National Institutes of Health in Bethesda,
MD was one of the leading proponents of it outside of Bell.  If anyone
still has a copy he does.
