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!

Hi folk,
I am still looking for a DQ696 to allow me to get ESDI drives going on
both my microVAX and 11/73 since the Webster RQD11 controller failed I
only have the one. I'd also like to get old of an RQDX3 since I built a
Gesswein emulator and have nothing to test it with :-)
Any help appreciated,
Nigel

Hi all,
After some discussion on reddit about russian PDP-11 clones, i made the (perhaps erronous) claim that the PDP series in general was cloned by the Soviets.
I’m aware that there was a lot of QBUS/LSI PDP-11 clones, and depite poor documentation, there is significant evidence of PDP-8 clones. Also, depite not strictly a “PDP”, the VAX series was also cloned.
However, i’m curious whether anyone has any evidence of either the 18-bit or 36-bit PDP machines being cloned? I imagine that given the rather lacklustre success of the 18-bit series, that there would have been less demand for an 18-bit PDP machine in the Soviet Union, but i find it quite hard to believe that no attempt to clone the PDP-6 and PDP-10 machines would have been attempted.
Does anyone here have any information on such clones?
Cheers,
Josh Rice
Found an ad from 1984 - poor resolution but gives you an idea of what the strap looked like. -W

Does anyone have a Philips P2000C CP/M luggable with the carrying strap?
I will be restoring such a machine in the near-ish future and mine is lacking the strap. Clear photos of the end fittings that slot into the machine, the dimensions of them, etc would be a great help in making something up.

I'm working on cleaning up a bit of battery leakage in a MicroVAX 3100
Model 10 and while it's apart I decided to look inside the PSU (an
H7822-00).
It's nice and clean inside with no bulging caps. What it does have is an
X2 capacitor, as shown here: https://photos.app.goo.gl/dpdqJ3tuGfsRDR3Y6.
It doesn't appear to be damaged and I can't see the word "RIFA" on it
anywhere but I can't see two of the sides because of other components
that get in the way.
So does anyone know for sure whether it is a RIFA brand or not, or do I
have to desolder it to be sure?
Thanks
Antonio

My apologies if this topic is a sore point for some of you. Their abrupt
closing wasn't that long ago.
Does anybody have any insight on what is going on there? The web site has
not been updated in about 2.5 years. The world seems to be moving on; it
would be nice to know if we're ever going to see the museum re-open, and in
what capacity.
I realize the people are gone and scattered and it's never going to be the
same experience if it re-opens. But there are plenty of us who still
believe in the need for such a place, and starting from scratch would be
difficult.

(Off-list replies are welcomed if that makes the discussion easier ...)
I have a box here of 14 DZ11 Unibus 8 line serial port interfaces. And I
have no clue why I have them.
Anyone need some? Otherwise I'll Ebay/recycle them.

The LCM has some of stuff (a Zenith Z150 PC computer, including monitor and an early paged memory expansion that I installed, a couple of Apple IIc computers and monitors, a printer, but probably more important, a bunch of original MS-DOS software diskettes and manuals from the mid-1980s to the mid-1990s (including several versions of MS-DOS, FORTRAN, MS Word for DOS, an early version of Lotus-123, and other earlier software) that I used to complete my doctoral degree and first start my college teaching position.
But I understood at the time that Paul's LCM was actually "buying" my computer stuff, as they reached out to me in interest to acquire the entire lot of materials (after I had emailed an availability list to this very same cctalk group) and accepted the prices I requested without question as I recall, plus I was reimbursed for all shipping costs. And so I interpreted the transaction at the time that I no longer had rights (other than visitation rights should I ever visited Seattle) to these items.
I may be unclear in my understanding from the time, but at the same time none of what the LCM received from me was so rare or unique as to my wanting to ever request it back again. I was thankful at the time that I had a place for this computer stuff to go. I would be sad, however, if any of it might be now in a dumpster or landfill, or has been sold to someone else, and so I guess I also don't want to hear that news either way.

Hi,
Does anyone have a copy of DAEMON Tools Ultra 4.x install file(s)?
I just purchased a lifetime license based on the documentation on their
site. The problem is that they don't have 4.x available for download.
I just need the install files and I'll use my personal license.
N.B. I need this to work on an ancient Windows XP system that I'm
messing with as part of retro computing.
