I saw a couple at DECUS Symposia in the late 1980s - they were fun to
play with, even if they didn't have good price/performance numbers.

They most certainly weren't. There were power tools here that had a
metal casing, were earthed and wired to a non-polarised plug. That was
well before 1970. And in Sweden.

After a poor turnout at my place of work, I canceled trying to hold meetings there. Instead, I created a discussion group for the Historical Computer Society. There are a few of us there now, and we are building a grassroots organization that way. This is a group to become a lot like MARCH (http://www.marchclub.org/) for the greater Atlanta / southeast US region. A few of us had our first meeting in a restaurant yesterday, so I think that is a good start.
More information is here - http://www.classiccomputing.com/CC/Meetings.html
Anyone in this area, please consider becoming a part.

There is currently a pretty big PDP-11/44 collection on Ebay (just
search for PDP-11/44). It is located in Milwaukee.
Will anyone here be bidding on the pile? If so, and you win, I would
be interested in one or both of the RK07 drives, but nothing else.
Reply off list...we could come to terms...

On further investigation, I find that if I open the full URL first, and
then shorten it down to the above, I then get the full sized picture with
no problems.
However, if I go straight to the short URL above, it fails with the
"Not found" error I mentioned in my previous mail. Google must be doing
something really strange.

OK, I've been studying the circuit diagrams and service manuals for
the Tektronix 4014 printer interface:
<http://bitsavers.org/pdf/tektronix/401x/070-2303-00_4014_4015_Service_Mar79…>
<http://bitsavers.org/pdf/tektronix/463x/070-1831-02_4631_Service_Nov79.pdf>
I'm starting a project to create a modern printer interface for the
terminal. This involves creating the optional target signal amplifier
board for the 4010/4014 and creating a microcontroller based board
that will drive the terminal like a 4631 printer and scan out the
image from the storage tube for digitizing as a digital image. The
amplifier board is what distinguishes a 4010/4014 from a 4010/4014-1
and provides the signals for the printer.
The original 4631 printer is a completely analog device that scans out
the storage tube and transfers the electrical signal to a dry silver
paper for printing. This design will treat the analog signal supplied
to the printer as a signal for digitizing into a raster image. I plan
on housing mine inside a 4632 video hardcopy shell with a modern printer
inside driven by the controller. Who knows, this project might make
those 4631/4632 printers useful again, considering that noone is going
to be getting a new supply of dry silver paper anytime soon.
I'm looking for other people that have hardware design experience to
join me on this project. All resulting EDA files will be made
available under a suitable open source style license.
Please reply to me off-list if you are interested in collaborating
with me on this project.
