After recently selling my ImageDisk system, and having a few spare older PC
mainboards - I decided to make another - I did find a board that seems to
have a decent FDC - it does all single density formats (many don't).
Alas, it is "slightly newer enough" to only implement one floppy drive
on it's interface - floppy B: does not appear at all to the system.
Ripping the cable off the front panel drive to connect an external one
is somewhat painful - Since the PC normally has a twisted cable to swap
Select1&Motor1 with Select2&Motor2 to put each set on Select2&Motor2 of
different connectors, I thought I could just use a flat cable and add a
switch near the PC end to switch Select1&Motor1 to go to either Select1&Motor1
-OR- Select2/Motor2 on both connectors with the internal drive set to 1:
and a cable coming out the back for drives jumpered as 2: That way I could
just "flip a switch" to choose between internal drive 1: or the
external drive(s) 2: (either would appear as A: depending on the
switch).
But when I try to access a drive jumpered as 1:, it does select, but the
motor doesn't turn on. This happens even without my "special" cable. If I
connect the drive (by itself) on the PC side of the twist on a standard
cable, the motor doesn't work. The twist swaps Select1&Motor1 to
Select2&Motor2 on the farthest connector, and since a standard drive is
jumpered as 2: - This should put the 1: signals to 2: for a drive in that
position - all other wires are "straight through".
It looks as if some other signals is expected to behave differently when
the drive is jumpered as 1: (I've tried this with a couple of different
drives) - anyone know whats going on?

Bad news. We had a big cleanup in our lab last year, and
got rid of a LOT of stuff. I'm pretty sure we had a 2922,
that was the CAMAC crate controller that may have been used
with the 2920. Was the 2920 the Q-bus board that connected
to a crate controller via a hand-made multicolor twisted
pair ribbon cable? I think that went out a LONG time ago.
I did have recently at home a KSC crate controller that had
an LSI-11 inside it, but I think that went to recycling
about 2 years ago. Sorry!

In a search I found a digital brochure for the Xerox 800.
The text is in Dutch. The text can be highlighted therefore I think it can be then sent to a translator.

Anyone know what's inside the Xerox 800? There seems to be little information online about any of the 800 series other than the 820. Based on the year of introduction of the 800, and allowing for time prior to that spent in development, I'm guessing that it's not microprocessor-based. (Whereas the 820 is.)

Friends,
The process of migrating the cctalk and cctech mailing lists to a new host in Chicago is underway. This evening, I've moved the list mail handling to the new server, and this message will be the first live test. Assuming this works, you shouldn't have to change anything to post to the list.
The green web pages, the old "pipermail" list archives, and web access to archives of new postings from this point still require a little work, which I hope to complete in the next day or two. I will eventually import the old pipermail archives into the new posting archive, but that may take a little longer.
The new hosting is provided by the Chicago Classic Computing group.
Many thanks to Jay West for hosting the lists for 20 years!

Long shot but....
I have in my possession a LaserMaster LX-6 controller. The controller allows achieving much higher res from a HP LJII then one would normally be able to (600x300 DPI vs. the standard 300x300 DPI).
If you are really interested can read more about it here:
https://books.google.com/books?id=2jkWJsu_9CoC&lpg=RA1-PA46&ots=HrKHEtLGTu&…
I have all the requisite HW but I am lacking the manual and more importantly the driver SW. I was able to locate multiple copies of the LM website on The Wayback Machine. Unfortunately, while some of the smaller files have been archived all the main EXE and ZIP files are missing. For example see:
http://web.archive.org/web/20000301145615/http://www.colorspan.com/support/…
I am wondering if anyone has any drivers for this card. A manual would be most excellent as well but drivers are more necessary. Thanks.

It's vaguely familiar.
Another part of the Rank organization, at one time, was precision measurement company Taylor-Hobson. I remember several of their their instruments in the metrology lab at U. Eindhoven.

Ditto.
I think this may be another of those US/rest-of-world things.
To this Brit, the only company I knew of with this name was "Rank
Xerox" and I had never heard of "Xerox" as a company (nor as a verb)
until I was an adult working in the tech industry and learned of Xerox
PARC and its role in the development of Smalltalk, OOPS, the GUI etc.
So probably roughly in my late 20s or early 30s.
"To xerox" meaning "to make a photocopy" was something I learned
around the same time. This is not a verb in British English, nor I
think in any non-North-American dialects of English.
