This is not quite last call, but it is getting close ...
We have 16 exhibits so far and we need a few more to make the show work.
(20 would be nice, 25 would be ideal.) The event is March 23-24th in
Seattle. Soon I'm going to start working on the exhibit floor plan, set
the event schedule, and start to do the prep work that makes the show
possible. But I need to know who is participating before I get too deep
into that.
If you know you are definitely going to participate then please help me out
and formally register. If you have questions or are on the fence then let
me know and I'll try to help you decide. Maybe this is not the right year
for you, and that's fine ... but if there is something I can help you with
let me know.
I'm not fussy but if you can exhibit Commodore 8 bitters or Amiga equipment
then I really want to talk to you. :-) (We seem to have a gap in the show
there. Amazingly, nobody is doing an IBM PC related exhibit either.)
A description of the event can be found at http://vcfed.org/vcf-pnw .
General information for exhibitors including pictures from last year, a
link to the registration form, and a FAQ can be found at
http://vcfed.org/wp/vcf-pnw-exhibitor-registration/ .
Thanks,
Mike

Excellent news. (Sorry I've gone quiet - I got distracted from the analysis
effort by trying to finish up the -11/34 ucode transcription effort.)
Is it really an MS11-P? Those are EUB memories; I don't recall offhand if
they (like the MS11-M) have a jumper to configure them to operate on the
UNIBUS.

I am about to get our IBM1627 (rebranded Calcomp 565) going but the pens in
the case is quite dry. What is the best method to refurbish those? What is
the best solvent to get the old ink out? What ink to refill with?

Hi folks,
I'm in search of source code for AT&T's System V Release 3.2.1, 3.2.2,
and/or 3.2.3 for the 3B2. Does this exist? Has anyone ever seen it?
Note that I'm not looking for the System V Release 3.2 Source Code
Provision for the 3B2 /310 and /400 -- I already have that. It was
absolutely invaluable when I was writing my 3B2/400 emulator.
The reason I'm so keen on getting access is that I have ROM images from
a 3B2/1000, and I'd like to add support for it to my 3B2 emulator. The
system board memory map seems a bit different than the /300, /310, and
/400. These max out at SVR 3.2.
I can't imagine trying to add 3B2/1000 support without the 3.2.x source
code.
I imagine there's some tape image somewhere that's a delta of files that
take you from 3.2 to 3.2.1, 3.2.2 or 3.2.3?

Hi - I am making some room. I have a two SGI Indigos. One of them is a R4K.
The second may be a r3k, but may be a r4k as well (I wont get a chance to
check til the evening).
Both will have ram/cpu/graphics/sled. If youre local, come and get them.
If no takers locally, I will ship for cost of shipping (but I wont get a
real chance to do this for a week or 2, if not longer).
Ping me if youre interested, thanks.
I have used Jorgs kit to get my 11/70 front panel running.
There is NO NEED to split the cables - for manual circuit, nor is there in the new
?cap? adaptor board.
I *THINK* Jorg has many cables and many panels and the split is a throwback
to some earlier work that I saw photos of.
My (wire wrapped, no using the new ?cape?) is at http://www.scotnet.co.uk/iain/DEC/1170/ <http://www.scotnet.co.uk/iain/DEC/1170/>
Flat 40 pins - no split.
I have not had time to document the process of the old or new board. All I can say is
that the kit turned a messy job into a fairly quick and easy one.
I can strongly recommend the kit to anyone.
It took me two nights with the circuit list and a wire-wrap tool to set up the board in the
link above.
Then an elasped day footering with the test software and scope checking signals etc.
With the newer 11/70 add on board I would think it would be a painless evening of work.

Greetings CCtalk,
? Does anyone in the Boston area know of a working 80-column
punched-card reader?
? I'm working with a researcher at Harvard who's come across some very
interesting election polling data from the 1960 Kennedy-Nixon race,
punched onto about 10,000 cards (five boxes).? That's too many for
manual transcription, but too few for an industrial-strength solution.
? The cards are in a professionally-managed university archive, so it's
not as easy as just throwing them in a shipping box and sending them off
to who-knows-where to be read.
? Some of the cards are in binary format, so I'm fine with some ad-hoc
Pythonic data massaging, if I can just get the bits read.
? If anyone in the Boston area has a machine they might be able to make
available, could you get in touch?
? That's fedorkow at mit.edu
? Thanks!
