Sorry my previous message seemed to be missing the text that I wanted
to send... see below...
I have what I believe is a PDP 11/23 in a cabinet with two RL02
drives. I rescued it from a company who were just going to skip it in
the 90's. I've never used it and don't have an OS for it but the
company had been using it up until the day the that I rescued it.
The machine is located in Bury St. Edmunds in Suffolk. If someone can
put this to good use then they can have it. I'll post a picture of it
up somewhere tonight to help identify it. I think it may have some
schematics with it as well.
Regards, Rob.

To add to this, there used to be a book on computer
engineering with

on designing a PDP of some particular nature. (It might even have
been a
PDP-11.)
Is it possible to persuade the writer of that book - a University
textbook I
think - to donate it to PUPS? Alternatively, does someone have an
updated
PDP-11 design that they would be willing to donate to PUPS for
anyone with a
soldering iron and enough time, to play with?
I'm thinking this would be the way to solve this sort of problem in
one fell
swoop, if as I suspect is likely, it is impossible to find a working
and
available PDP-11 in the UK.
Just my 0.02c worth - and my, hasn't inflation risen ... ;)

Having long ago got rid of my collection of
ageing British (super)
minis, I realise I'm missing them, though I'm not sure why. I can't
pretend any more that something running 4.2BSD is really practical,
so I'd like to get something really impractical, like a pdp11.
What I'd like to be able to do is run 7th edition or thereabouts and/
or 2.11BSD on something which is not too large (so full-height 19"
racks are out). I'm not interested in emulators. It looks to me
like there are such systems - for instance the recently-discussed
11/23 (or 11/73) looks practical, other than being in Utah.
So I guess I have two questions:
Firstly is this a practical thing to do in terms of reliability of HW
etc? I finally gave up on the previous lot of machines at least
partly because disks &c were just so flaky that it was too painful to
keep things working (also we're talking full-height 19" racks in some
cases so they were a bit, well, big). I don't want to spend my life
trying to source ancient disks etc (though I'm clearly not expecting
things to be as reliable as good, new modern kit).
Secondly, does anyone in the UK (may be there is no one but me, of
course...) have any hints where I might look and what I might expect
to pay. I've looked on ebay but I'm a little nervous of what I might
get that way.
Thanks
