Mine came from
Cambridge University at about the same time, and AFAIK
they werre used for much the same purpose -- that is using PDP11s as
frontends to an IBM mainfram. The PDP11s were stufferd iwtrh comms cards
-- DMC11s, DMR11s, DUP11s, even the odd DJ11 (16 channel asynchronous
mux). Others wanted the 11/34 CPUs, but the (interesting to me) comms
stuff all came home with me ;-)
Coincidence or not I don't know, but the two at Leeds were also on
11/34s, stuffed with serial I/O, mostly Emulex CS111s, and booting off a well-worn RX02. I got one of the 11/34s and some
serial cards, plus a
I am pretty sure the Cambridge University machines ran from RK05s, or 3rd
party equivalents.
few bits and pieces.
Is the CS11 the onw where there's a Unibus board full of 2900 bit slice
chips liked to distribution panels which contain the UARTs are well as
the line driever/receiver ICs? I have one of those in my 11/44.
Leeds also had a couple of brown boxes which were
essentially 11/73
machines (each in a 3U-high third-party cabinet) with a rather odd quad
QBus ethernet card made by Camtec (as in "Camtec PAD" or "JNT PAD"),
As an aside, I have JNT-PAD and its unser manual soewhere. Odd device,
it appears you can save the configuration on an audio cassette recorder...
