It's time for another batch of exciting stuff from my collection to find
its way into yours!
Today's batch:
Compaq Contura 4/25
Compaq LTE/286 Laptop
Compaq Portable III Operations Guide + System Software
Packard Bell PB414A Multi-Media PC
Radio Shack 1982 TRS-80 Microcomputer Catalog No. RSC-7
There were only 2 11/45s that I knew of. The first was the “front end”
that sat in front of all of the terminals and allowed connection to the
various 10s (at the time there were 3: 2 KA10s and a KL10), C.MMP and
CM*. The other 11/45 ran the XGP...
They had moved on to a Xerox 9700 and
11/40’s were pretty ubiquitous at CMU when I was there and at least as far as I
could tell, were all configured pretty much the same (in that they all had
custom writable control store). I personally dealt with 3 different sets of
11/40s:
A single 11/40 with WCS that I used for doing some
First off, I've had a couple of follow-ups on these units, so they are
spoken for at this point.
The member with first dibs has also offered to scan the docs and see
that they make their way to Al.
I was wondering if these were c.mmp cast-offs? Guy: I encountered these
in the CMU computer
I don’t know. It would be hard to replicate because of the custom HW and the
custom uCode that ran on the 11/40s. I even think that the 11/20s were
modified as well. So trying to figure that out would be “interesting”. ;-)
There is documentation on bitsavers that covers the custom uCode HW

It's been a long time since I've heard that reference. Did any of that
The only thing that I believe would have used these would have been C.MMP. It
had 1.2MB of memory on it when I was there.

I would be interested in putting up the later docs
I wonder if Guy remembers what these were used for at CMU

The Microram was a multipurpose solid state memory chassis sold by EMM
(Electronic Memories and Magnetics) with what we called later in the 1970's a
"personality board" that plugged it into each different CPU's backplane. They
sold a similar system (maybe even plug compatible at some level)
