New hobby thing. ;)
Wildcat! 4 running on it, stock out of box config. If you don't see all the
menus except for help and send to sysop, wait till I validate users. When I
get back home i'll set it to give non-validated users more permissions,

After stating that I expected TSX Plus to be available generally to the
collector community this week, I have had a number of folks request
access to TSX plus via private FTP.
Please be a bit patient and wait for me to post it to a new website I'm
in the process of creating. I now have full agreement from S&H to
generally release TSX Plus, COBOL, etc., to the collector community via
a simple download.
BTW: I have converted all of the original documentation, which was in HP
print file format to PDFs for easier and more general use.
Over time I will likely be able to release some of the utilities, etc.
that S&H used internally with TSX plus. Some time ago S&H gave me all
of their RL02 packs and a SMD drive with everything they had related to
the PDP-11 version of TSX. (They have a current version of TSX for X86
systems which is NOT free and is NOT part of this release).
Over time, there may be a project to scan the source listings and
recreate TSX Plus source code. (The source listings are available on
bitsavers.org (pdf/dec/pdp11/tsxPlus/listings/). Unfortunately, we are
missing the MACRO definitions in the source listings. Some of us are
working on that issue. (Note: All of the original PDP-11 source code was
accidentally lost by S&H).
I will also make available any software that other folks submit to me
related to TSX on my website.

Does anyone happen to have documentation, schematics, or software for the
Quay 900? It's a system based on the Quay 90F/MPS single-board Z80
computer and two MPI double-sided 8-inch floppy drives.
The drives are MPI part no. 77618022, apparently a 9406 variant but not
listed in the drive manual on Bitsavers. I suspect the pinout is close to
the SA800/850 pinout (industry standard), but I was surprised to find that
none of the variants in the 9406 manual have a pinout similar to that.

The thing that I wonder about it, for that to be true, is something that
someone (sorry, to lazy to look in the archive to give proper credit) pointed
out, which is that that CPU is only two boards, and the memory management,
including the PARs, is built into one of them. So how could one extend a PAR
>from 12 bits to 16, when there's already 12 bits buried deep inside the CPU?
That's the part that I can't work out...

You and me both! :-)
I have this dream of one day having an 11/45, with the Enable and the optional
cache. Now that would be a sweeet machine: most of the capability of an 11/70,
but a lot less power draw. But I'd need the documentation to see how to
connect it up! :-)

OK, if you can, that would really be great; if either i) it's still together,
or ii) there are pictures, it would fill some of the key knowledge gaps.
In particular, i) what kind of backplane is it plugged into, and ii) what is
the UNIBUS edge connector on the card connected to...
The silence may have led you to believe that it was all over. Oh no...
The 10th Vintage Computer Festival is a GO!
Bigger, bolder, nerdier than ever, a wonderful way to tack on our
second digit, VCFMW10 will be held August 29-30 at the Holiday Inn
Chicago-Elk Grove Village. A remarkable convergence of amenities and
price have come together in this spot. Among the features:
- A single 4550 sqft banquet hall - at long last, VCFMW and ECCC shall
truly be one!
- First-floor facilities - no more elevator rides or Level of Discharge!
- 11'x12' loading doors that open direct to the parking lot - you
could drive a truck right into the ballroom, but don't!
- A separate room for talks, videos, quiet time, etc - like we're a
real conference or something!
- No (known) conflicts with holidays, wives' birthdays or other local events!
- The quaint, vaguely Blade Runner-esque surroundings of industrial
parks, truck depots and factories - just the way we like it!
- An on-site restaurant, pool, exercise room, outdoor firepit/smoking
area, shuttle buses to/from the airport and Woodfield mall, close
proximity to fast-food and the two greatest Chicago eateries,
Portillo's and Lou Malnati's! (Seriously, those two alone are reason
enough to attend.)
I have updated the http://vcfmw.org web page and FAQ with most of the
information we have so far. Please give them a read before posting
questions. Hotel room rates will be slightly higher than last year's
$79 at the Fairfield Inn; I am still negotiating the block rate. Due
to the restaurant being on-site, there will be no continental
breakfast. Sorry :(
Now the hard sell: all of this geek-luxury does not come without a
price. Some of you know that the deal we had at the Heron Point was
extraordinary and unheard-of in the event hosting business. Since the
HP no longer rents to the public, we were faced with the choice of
resting on our successful nine-year record or figuring out a way for
the show to go on. And go on it shall...with your help. Without
getting into specifics, the cost of putting on VCFMW has more than
doubled - and we are getting a bargain if our comparison shopping is
to be trusted.
Donation links have been set up on the main VCFMW page for PayPal and
GoFundMe sites. Please use the GFM only if you do not have a PayPal
account, as GFM charges us a fee. If you'd prefer to donate in
person, contact me directly. I will get you a receipt (sorry, we're
not a 501.3c yet, so it won't be tax-free.) The main site features
our non-patented Donate-o-Meter which will (more-or-less) track our
progress. We have a lot of time to reach our goal as payment is not
due until the day of the show.
Extra money raised will be either spent on bonus features for the show
(more space, pizza bar, etc.) or put into a fund for next year. We
will engange with the community as much as possible before making any
decsion regarding extra funds.
There will be much to do between now and August - a new floor plan to
design, tables to allocate, speakers to recruit. But our first big
task is one where everyone can help: let's get the word out! Many of
you are on forums that I am not, so spread the news: the show will go

I'll try to check tonight when I get home... spreadsheet says I have 8
Xylogics SMD controllers... have to see if any is an XY472.

My soon to arrive HP 2112 has a 2102A memory controller and 3x 2102A cards
of 8k memory each. I suppose I could add more 2102As to fill it up the 5
remaining slots and bring it up to 64k. But the recently posted IO manual
says it can support way more - up to 1.28M. I'm not sure yet how the HP 1000
memory works. Can I put larger (>8k) capacity HP 1000 memory boards in there
to expand memory beyond 64k? Do I need to replace the memory controller with
one that matches the larger capacity cards then?
If I could afford it I wouldn't sweat the shipping cost.
I think someone had posted what board did the graphics. Has that ever
been given consideration for being added to SIMH for the 11?
I'd love to run Lander, which I think is running on the system as shown.
To Al: There was also a system like this at USL, which I wish had been
conveyed to you. I suspect it was not. There was a new in the box
replacement CRT because someone had had the system halt and burned the
phosphor. You had to watch the system and never let the dot stop. If
it stopped at a spot on the phosphor in the on position, you'd etch the
Ours (USL) never ran anything but Lander, so until someone with a
project came along, we were saving the tube. The burn didn't affect
lander much at all.
Just acquired a NeXT 68040 cube computer. It's way cool, but the responsiveness is unimpressive - I'd call it pokey.
All 16 RAM slots are full for 16MB, but sixteen 4MB RAM sticks may help the speed.
It has an internal HD, as well as the magneto-optical drive.
One things it's missing is the monitor stand - does anyone have a spare stand for a NeXT N4000A monochrome monitor?
