If you just need the boot image, I think you're looking for a file called
"Xncd17c" - I use Xncd19c for my 88k-based xterm (or did, last time I used it
for anything!)
These used to be freely available on ftp.ncd.com (up until 2 years ago for
sure) in their own "older units" directory tree but seem to have vanished.
However a quick google returned:
http://www.stat.wisc.edu/p/stat/tftpboot/cs/Xncd17c
... which may be exactly what you need.
Set up a tftp server somewhere with the image on and you're away :)
cheers,
Jules

There is one last chance to buy a 3inch reel tape for your B9.
I have ten tapes, and once they are gone, thats it.
See ebay Item # 3026315320 for a dutch auction.

These are toggle switches with two closed positions and three contacts,
ie two on positions and a common ground in the middle.
My problem is finding the correct dimensions, ie spacing between
connectors as well as height above the board and the length and width
of the "neck" to protrude through the panel..

And then some museums don't.
There are many techniques to avoid static displays.
* Rotating the equipment on a turntable with the back open.
* Recreating really old equipment or high wear parts.
* Equipment displays with interactive java simulation of
the equipment running nearby.
* Faking the output display on unpowered equipment with
the 'PC behind the curtain'.
* Or just using equipment that is still some what available.
And don't forget the importance of the the right lighting
and sound effects. :)
I am currently trying to help a gentleman restore
a EAI TR-48 desktop analog, from the early 60s, on
display in the Retro Beep Computer Museum at Bletchley
Park. He wants to run a repetitive simulation for
visitors to see.
I asked him if the recreated Colossus is actually
operated for vistors to the museum. He replied:

FAQ. This is the result of having a 9302 terminator, whichg asserts
SACK, and a missing NPR jumper somewhere. Either you have a card
missing, or you've put a card that doesn't pass NPR into a slot where
previously there was a card that did (or you've put a small grant card
where you should have a full-size one). Ethan mentioned this in
response to one of your posts recently, and Tony (on more than one
occasion) explained in detail why this has the effect it does.

I just retrieved an Altair 8800B from long term storage. I blew away
the dust, checked for loose connections, and finally powered it up.
Lights flickered to life, and then smoke poured from the front panel.
I pulled it apart, and found a very crispy capacitor number C4 on the
front panel card. My first problem is that this capacitor is so crispy
that I have no way of determining the proper value. It is (was)
connected to a voltage regulator marked "F 79MO8 AUC 7535"

Hmm... Having seen this on eBay:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=2731022229&category=12…
the nameplate from an ICL 2950, weighing over 2Kg alone, and had my
curiosity nudged, I was wondering if anybody knew of any pictures of the
beast itself? A quick google found me a bit of info, but no pics yet.
Hmm.. I've got a nameplate stuck to a 5.25" disc box in the cupboard from a
Ferranti "EWTS" system (Early Warning [Tracking|Training] System, I forget
which, and google doesn't help at all) ... Picked it up while I was an
apprentice there - now that was fun, wandering round the factory, about
1982/3 - I seem to recall computer generated ships and stuff on one
system. Amazing graphics for the time.
It's a shame how little of the old stuff still exists.. I also used to
"play" on a Data General Nova, must have been about 1980, at the college my
Dad taught at; I sometimes wonder whatever happened to that..

If you are interested in unloading one of those Sony drives, I'd be happy
to take one. I have an original external 400K drive for the Mac, and its

wanted to unload a spare, I'd love to get my external drive working again.

I had a Trendata1000, which was similar to the IBM 2741. It had a real IBM
Selectric Terminal with Trendata's custom electronics. Many members of The

I still have the IBM reference manual for the 2741 Communitations Terminal.
It is 20 pages on how to write a driver for the 2741. I also have the

I normally used it for a printer but it also worked as a terminal.

We have 8 warehouses stuffed with mainframes and minis. Around 120 of
them in total. This belongs to the Norwegian Museum of Science and
Technology, and with so many machines, there's BOUND to be a -10 there
too :). On average, the museum recieves a query for pickup once a week.
They also ran a mainframe on public display 15-20 years ago, but this was
a Norwegian machine (NORD-1 i think, brilliant machine) and the people who
knew about it didn't have the time it took to keep the mainframe going.
This machine has been upgraded to run PDP-9 software, and has a switch on
the front panel named "USE" with the options 7 and 9.
It also had a homemade Automatic Priority Interrupt, nicknamed "Poor man's
API".
It has an oscilloscope display, two TU55 tape drives hooked up to a 550
tape controller, and the EAE (Extended Arithmetic Element).
Picture at http://tore.nortia.no .
Yes, we have a full set of schematics, except for one board (and with
godly precision, this is the one we need), the Teletype Interface Card,
seated inside the teletype. It is numbered 1818(twomoredigits).
If I restore this -7, the Museum might let me inside one of their
warehouses, and maybe restore a timesharing system, like, for instance,
a -10. But, I'm going to keep focused on this task (for now ;) My dream
has always been logging on a timesharing system with a VT terminal.
IF the warehouse has a 15 in it, i'll ask them very nicely for a TC15. Who
knows. We do have tons of -15 documentation (ask me not why) at the
University, and even some -15 OS DECtapes.
Thanks a bunch!!

Hi,
I saw a forum on line and your email was there. I was wondering if you could solve my problem.
When I turn on system, the screen says turn off game before inserting cartridge. It does have the coleco logo so I know it has power and rf is working. I did what it said and I also hit the reset button but I get the same screen. I also cleaned the contacts on the cartridges. Do you have any idea what is wrong?

Hi
All make the assumption that you must make 8 bit/16bit
or, in your case, 20 bit. One can make a 1 bit alu that
can have data width controlled by instruction. It may
not be fast at math but much processor time is consumed
just looking at true/false. If your model doesn't require
passing data through the alu for mem/mem and mem/io moves,
a single bitter makes sense.

In response to the question of which came first, Non-Linear Systems or,
Kaypro Corporation. I worked in the purchasing department of both companies during
the 1980s. Kaypro Corporation was a division of the parent company Non-Linear
Systems which was established in the 1950s by Andrew Kay, who was the
innovator of the digital volt meter. In the early 1980s, Non-Linear Systems began
building the Kaypro portable computer after Kay's Son-in-law, Jonathan Badder, a
local architect in partnership with Kay's Daughter Janice Kay, expressed a
desire to have a portable computer to take out to job sites.
When the Kaypro portable computer became an overnight success and far
eclipsed the volt meter business, Kay established the computer division known as
Kaypro Corporation. Both products were manufactured simultaneously at the Solana
Beach, California location at 533 Stevens Avenue, near the Lomas Santa Fe exit
of Interstate 5.
When I joined the Company in early 1983 we went from about 50 employees to
over 500 within a year. Andrew Kay was a very interesting and forward thinking
employer, hence the name of his original company Non-Linear Systems, since he
prided himself on non-linear thinking. He was a very health conscious
individual, and had a juice and salad bar installed, which all employees could dine at
for only a dollar. He tried to treat everyone as extended family, and believed
that a work environment that incorporated nature in it's design would produce
better work. Therefore, every office had windows in front and back, with a
row of trees and grass between each building. It required some considerable
walking to negotiate around the plant, but he believed that walking promoted good
health. He also was very interested in personal intellect, and in the early
stages of Kaypro, everybody had to take a sort of IQ test that he designed and
administered. He also made versions of the Kaypro that were marketed as the
"Tutor Computer" that were a learning aide for children.
It was a fun place to work in the early days, with a very young average
employee age. We were encouraged to work hard, and to play hard. Lots of parties,
barbecues, intramural sports teams, and the like. It was fun to go to work
everyday. During the push to increase shipments before the Company's initial
public stock offering, we received some very generous bonuses, including a
Christmas bonus equal to a month's salary, which we received around December 15th.
In the latter 1980s the company was plagued by poor quality, serious
inventory management problems, a revolving door on upper management that included a
long parade of self-impressed no-nothings that couldn't break free of their
linear thinking, and a serious lack of continued product innovation. After the big
boys like IBM jumped on the bandwagon of the PC and laptop market, Kaypro
just couldn't compete. All these factors and a few more, including the employment
of Kay family members in key positions that did not have the capabilities of
founder Andrew Kay, eventually led to the demise of Kaypro. I think that the
business section writer for the San Diego Union Tribune said it best when he
penned the phrase "Too many Kays and not enough Pros."

I have a tube digital clock, which I made out of a Beckman Berkeley
counter. The counter uses decade modules, each with four tubes used as
flip-flops, and ten neon lamps which display the count on a numbered 0-9
plasic window. The HP modules work pretty much the same way as the
Beckman tube modules, although the binary to decimal decoding scheme is
different in that it uses light and photoresistors instead of resistor
networks.
http://www.mindspring.com/~jforbes2/tubeclock/index.html
shows my clock.
The counter modules could possibly be used as the basis for a tube
computer...maybe. I have a bunch of extra modules. I believe my
brother has the schematic for the HP counter that uses the nixie
modules, and he has one of the HP counters.
