  Maybe the newsgroup died of boredom - the last posting was April 25th.

  Any CPU with 124Kw of parity memory, KW11-L clock, DL-11 console, EIS,
and an RM02/03/05/80, RP04/05/06, RD31/32/51/52/53/54, RK06/07, RL01/02,
or RA60/70/80/81/82/90 disk.

  That means the PDP-11/23/24/34/35/40/45/50/53/55/60/70/73/83/84/93/94,
by the way. I believe that only excludes the PDP-11/04/05/10/15/25, which
leaves you a _large_ number of choices 8-).

	Wrrong, you forgot the 11/03 (or LSI11 & LS11/2).

Quibble:  RSTS runs on the 04/05/etc.  RSTS/E runs on the 23/24/etc.  ;)

Don't forget the PDP-11/44 (maybe even 11/23+ -- my memory is flaky about 
such ancient history :-).

  Yup, several folks have pointed this out. The funny part is that in some
areas of DECUS, I'm known as "Mr. 11/44" - if you were at the 20th anni-
versary PDP-11 College Bowl, you know why 8-). Besides, I have 3 11/44's
running here...

  Others have mentioned the 11/34A and the 11/23+, which I lumped under 
34 and 23, and the SBC-11/21, which was sold as "SBC", not "PDP", so I
don't think it counts, and the LSI-11/03, same thing.

Hey, to whomever wants to run RSTS, I have an 11/34a here, 
with two RL02 drives, just the thing for running a little 
RSTS at home (version 8 or 9 or 7, maybe not 10...).  It
worked a while back, now it is sitting on a pallet, looking
lonely, knowing that if someone doesn't take it home soon,
it will go to meet its maker (yeah, we can drop it on Mr. 
Olsens front lawn, if the guards don't shoot us...)

Seriously, you want this thing?  As is, Where is, Newton
MA.  Maybe a token $10 charge or something to keep the 
gods of commerce happy.

Gosh.  I'd take a free (or even $50) one if it was here in the midwest.
Too bad you're too far to just go pick it up this weekend....

I remember that machine, and the software that ran on it, very fondly.

You are all making fun of the venerable PDP-11 series. We here at 3M
Camarillo California are running many PDP-11 series (44,70,23,73) and
getting the job done as always. Even our 3M comrades say "PDP what???".
A DC3 may look ugly but it still flies and gets people from here to
there. Besides RSX11M+ has withstood the test of time superbly. The
hardware and software are sturdy, simple, and reliable. What more can
you ask?? Look also at OS/2. Who did Microsoft pick to finish the job
but Dave Cutler the father of RSX11M+. Also, RSX11M+ has multi-processor
commands in its reportoire! There have been at least two multi-processor
PDP-11's and if it weren't for the necessity of selling VMS I'll bet you
would have seen a proliferation of multi-processor PDP-11's. The PDP-8
and the PDP-11 will go down in history as two milestones in computer
progress. Already the PDP-8 is one of the historic turning points in
the IEEE 25 year edition of major milestones in progress!

 Sorry, Terry - I did not know you were known as Mr 11/44, and 
unfortunately I missed the 20 Anniversary PDP-11 College Bowl,

	HOWEVER you and your colleagues are invited to come to a 
Weekend workshop and Seminar AND 21st Birthday Celebration in 
Sydney, AUSTRALIA on 12 and 13 October, 1991 and tell us too.

see COMP.OS.RSTS and COMP.SYS.DEC and COMP.SYS.DEC.MICRO, etc for 
more details of the event and call for participation.

Regards, and thanks for your help to all PDP-11 users, John G.

You both missed the obvious: 11/20 (the original)...
Sheesh! Some people :-)

But I don't know if you can run RSTS/E on the 11/20...
Anybody?

  There was a typo in my original posting - "25" should have read "20".

You can't run RSTS/E on a PDP-11/20 but you can run RSTS-11; in fact
the original release of RSTS was on the PDP-11/20.  As I recall, we
claimed that a 28KW PDP-11/20 with two RK05s, DECtapes and a DH11
was suitable for 17 users.
