I'm still looking for an ASR-33 teletype, an LA36
DecWriter, and a VT50 DecScope for my 1977-78 PDP-11/40
computer center "reincarnation" project. Does anyone
on this list have any of these items that they would
be interested in getting rid of?
Also, another item that I need to make the project
complete is an HP 7200A plotter.
If anyone has any of these items and wants to get rid
of them, please contact me off-list.
Thanks,
Ashley

VT50? Unless you're desperate for 12 line displays, I'd suggest a
VT52 -- essentially the same vintage but 24 by 80, upper/lower case --
a far more useable device.
If you want older, go for the VT05, that gives you a full 20 lines not
to mention a rather cool looking device.

I've got a few VT52s. I was just looking for a VT50 because that's
what we had in our 1977/78 computer center and I was trying to
duplicate the environment as closely as possible. We did have a few
programs (that I still have and am loading on our recreated system),
that were written specifically for the VT50.
One of these was TVTrek, a VT50 version of the Star Trek game.
There are others, such as VT50PY. All of these should work fine on
a VT52, but they will only use the first 12 lines on the screen.

Any bites on the LA36 front yet?

Actually, if you respond to the VT50PY prompt:
Interval? 5/24
It will use 24 lines (or whatever number you specify) and update at 5
second intervals (again, or whatever interval you specify).
Also note that the 15 switch needs to be raised (or "d sr 100000" in
SIMH) in order for the performance collection code to dynamically
keep track of interesting things. [You did SYSGEN in the monitor
collection code?]

I'll have to try this. I've never used the /lines parameter on VT50PY.

I don't remember this question during SYSGEN. What does this do
and how can I look at the "interesting things" that are collected?

It sounds like you're pretty "into" RSTS. What kinds of system(s) do
you have and what versions of RSTS are you using? I just copied a
SYSGEN of a RSTS V7 system from my simh system to a *REAL*
RL02 on my 11/34 (using that handy program, VTServer), along with
lots of custom mods to $LOGIN, $LOGOUT, and other things that
were unique to our late 1970s implementation. I've used $REACT
to create our original PPNs for all of our old crew and the retired
professor who ran the computer center. I've booted the 11/34
from the pack and everything seems to work fine.
I've set up all our
custom CCLs and LOGICALs, and I need to create another RL02
pack for all our additional stuff like the GAME: directory, which I
have loaded with all those old BASIC games, as well as the BASIC-
PLUS version of ADVENTure, and some custom stuff like VT50
versions of games like Star Trek, which one of my friends put together
back around 1976.
I'm working on getting an 11/40, so my reincarnation of the system
will be more close to the original, complete with blinking lights and
toggle switches. Our professor modified $LOGIN so that you
could not log in to a privileged account on any KB other that KB0:
(the system console) unless one of the switches was "on". I have
this modification made to our copy of $LOGIN and have tested it
in simh. I've also implemented a program, $WAITS, which our
professor wrote. It runs as a detached job and wakes up ever
10 or 15 minutes and collects statistics on system usage, and also
logs off "idle" terminals.
I will stop rambling now.

There is a document that explains all of this. Go to
<http://pdp-11.trailing-edge.com/rsts11/rsts-11-101/> and grab the
DECUS.DOC file. The relevant part is "RSTS/E Statistics Collection,"
Author: Martin Minow, Date: November 18, 1976. In this document he
describes that to enable these, one must answer the SYSGEN question
"long or short question format" with "L/Q" or "S/Q".
Afterward,
switch register bits 0 and 15 control various aspects of data
collection. I believe this information is valid for RSTS versions 6
(starting in c?) through 9, though I can't confirm it.

I'll accept that :-)
I have one each of /73, /84, and /70. I'm still working on bringing
the /70 back to life. RSTS versions are available for hobbyist use
through 9.6, I believe.
I am trying to put together a comprehensive archive of RSTS
distributions and make this available to the community.

I believe *many* sites had similar modifications. Also see DYNPRI
from the same URL given above.
We must be roughly contemporary. My first experience with RSTS was
in '75 using the Oregon Museum of Science and Industry (OMSI) machine
while a student at Lewis & Clark University. I too am trying to
recreate an environment, but not that particular one. I'm trying to
put together a V7.2 system on the /70. It's been interesting (!)
trying to assemble all the pieces.
If you need any help, feel free to ask. Good luck,
John
