Hello folks,
I was (finally) lucky enough to acquire an Altair 680 back in November, and I have been able to get it back up and running, too.
Now that I have a fully working stock Altair 680, I am interested in acquiring expansion boards for it. If anyone has any Altair 680 expansion boards, especially a memory expansion board, that they are willing to part with, please let me know.
Thanks for listening.

So, I need to debulk my collection. A few years ago I took about 1/3 this much to the Foothill (now DeAnza, I guess) fleamarket and came away with $2k, which almost covered the cost of the storage locker it had been in! What you do with it would be up to you.
I've got about 15? 2x2x3 ish plastic totes full of cables, floppies, development tools (pascal, tmon) and there's an apple //e, several //c, se/30, classic, hard drives. LocalTalk connectors. All fairly clean and non-smoking. I think there's a mac rom emulator, an Apple // CFFA card, probably a puppy or two.
Must take it all! It's probably two pickups worth or one uhaul. My place is in downtown Felton, should be easy to park and load up although I'm physically limited in what I can do to help. Shipping is not an option unless you arrange a crating / hauling company.
Please reply off list for best results.
Cheers,

I think the latter may be true, I have this vague sense that the two DM
machines were never interonnected the way the AI pair were.
For one, the DM people didn't have a bunch of oddball hardware connected to
their main machine, the way the AI people did. (There was a special Evans+
Sutherland display processor, but that's about it. The ITS sources will
probably have a complete list, until the DM configuration section.) They also
didn't have as deep a bench of hardware people.
Also, I remember reading somewhere (it was decades ago, sorry, don't remember
the source) that AI's paging box was subtly different from the one on DM; the
AI one could IIRC, address 4 'moby's (a full PDP-10 address spare), and two (I
think? I'm pretty sure all the KA's had two moby's of main memory) were used
for the Fabritek 2-moby memory, one was for the PDP-6 (so the KA could see
into it) and one was for the PDP-11's. (AI had a number of PDP-11's attached
to it - one to drive the Xerox Graphic Printer, one to drive the Knight TV
system, and I think maybe one more, the so-called I/O -11 - or was that on MC,
which had two -11's - the standard KL front console -11, and I think one more?
I'm can't quite remember, although I'm pretty sure neither DM or ML had any
-11's. Anyway, on AI, the KA could see into the memory of its PDP-11's. If you
look at the ITS sources this probably is all laid out there.)
So probably the DM -6 and -10 were two separate machines.
> MX kl10 (expand ML group to high performance)
Actually, this machine was named MC when it first arrived, and kept that name
until its 'replacement', a KS, arrived, _many_ years later. (They didn't want
to give the new machine a new name, since there were a ton of mailing lists on
'MC', and it was easier to swap the machine names.) It was renamed 'MX' at
that point. It was called 'MC' since it was bought for the Macsyma Consortium
(part of LCS, not sure if it was part of the ML group, it might have been).

I'd pay $99 for one, but it would have to through a different channel
than eBay.

That's more than I'd _like_ to pay, but I don't have a lot of data to
compare it with...

Mark -
I worked for an Apple / IBM / network dealer, during graduate school (1983-1985).
The Corvus OmniNet solution was actually more popular for the Apple II --
especially with elementary schools (which was over 50% of store's Apple business).
Apple, as you noted, had multiple network solutions (LocalTalk, AppleTalk in 1985) during the 1980s and Macintosh introduction (1984).

In many ways, Steve Jobs "missed" the significance of networking for Macintosh launch (as did Microsoft with DOS) in this period ... even though he saw Xerox implementation, that eventually became 3Com.

Amazing! thanks Mark! Hope they are back in production soon.
Great to be able to have the II hooked to the Internet!

There are the Uthernet boards:

Looks like the Uthernet II is not in stock right now. I might get on the
waiting list for the text run, so I can play with one. But I'm still
interested in playing with the vintage AppleTalk stuff, anyway.

C++ inventor Bjarne Stroustrup, Ph.D., Enigma machine expert Tom Perera,
Ph.D., and a panel discussion by computer historian Bill Degnan on the
40th anniversary of appliance computers featuring the Apple II,
Commodore PET 2001, and TRS-80 Model 1 will be the keynote sessions for
Vintage Computer Festival East XII, March 31-April 2, in Wall, New Jersey.
The event is produced by Vintage Computer Federation (www.vcfed.org), a
national user group devoted to enabling hobbyists and spreading
awareness of computer history. The Federation is a 501(c)3 non-profit.
Stroustrup (www.stroustrup.com), who developed the C++ programming
language at Bell Labs starting in 1978, will discuss "The Origins and
further Evolution of C++" on Saturday morning, April 1. He is currently
a visiting professor of computer science at Columbia University and a
managing director in the technology division at Morgan Stanley. His talk
is sure to be an excellent follow-up to C language author and pioneer
Brian Kernighan, who spoke at VCF East X in 2015.
Perera's company, EnigmaMuseum.com, is in the business of hunting for,
researching, restoring, and selling Enigma machines and related items.
His talk, "Inside the Enigma: The history, technology and deciphering of
an early laptop computer and the real story of the Imitation Game" will
be presented Friday, March 31 after lunch. The World War II German
Enigma was arguably an original form of laptop computer. This talk will
explain the history and technology of the Enigma and link it to the
movie "Imitation Game" which tells the story of the cracking of the
German Navy Enigma code and the extraordinary contributions of
mathematician Alan Turing to this endeavor. In order to keep the
audience interested and involved, the movie has allowed some
inaccuracies and omissions in the history and technology and in the
masterful portrayal of the eccentric mathematician Alan Turing by
Benedict Cumberbatch. This talk will trace the actual story of the
Enigma and the cracking of the Enigma Code and attempt to fill in some
of the Enigmatic aspects of Alan Turing's personality. Perera will also
give a more technical demonstration of how the machines work and a
real-time disassembly of an Enigma in a separate session that day. He
will give further demonstrations and will offer for sale his Enigmas,
Enigma simulators, other historic cipher machines, books, Enigma Library
CD-ROM, and related items on Saturday and Sunday. Perera was formerly a
professor of neuroscience at Columbia University, Barnard College, and
Montclair State University.
Degnan (www.vintagecomputer.net) is a co-founder of the Mid-Atlantic
chapter of Vintage Computer Federation, a professional programmer and
web developer, and formerly taught computer history at the University of
Delaware. At his panel, "1977: The year of the appliance computer"
you'll learn about the launch of the Apple II, Commodore PET 2001, and
Radio Shack TRS-80 Model 1. Bill will guide the discussion to explore
how the appliance computer facilitated the expansion of computers as an
appliance into small businesses, schools, and the home. Panelists will
be separated into three groups each representing the Apple, Commodore,
and Tandy/Radio Shack perspective. The panel will respond to questions
and share their knowledge and personal experiences. The discussion will
continue from 1977 through the milestones of 1980s 8-bit appliance and
home computing.
All three sessions will be 90 minutes which includes audience Q&A.
Further details will be shared as the event nears.
