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. smp -- Stephen M.

Bounty: Motorola Tango

by cctalk＠snarc.net

Anyone have a Motorola Tango? It's a two-way pager from 1995. If you have one, then contact me privately. Can't discuss this on the list.

Felton, CA: Free kit - compact macs, //e, //c, etc

by salgernon＠me.com

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, --sma

PDP-6s at MIT

> I suppose it's likely they both used the same master/slave > configuration. However, there's one thing I found that may indicate > that the DM machine went in an other direction. 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). Noel

WTB: Apple II Workstation Card

by w9gb＠icloud.com

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). LocalTalk https://en.m.wikipedia.org/wiki/LocalTalk AppleTalk https://en.m.wikipedia.org/wiki/AppleTalk --- 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. greg w9gb === > After playing with my Apple IIe all weekend, my new obsession du jour is to network it > with my vintage Macintoshes.

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

VCF East keynotes: Enigma, Stroustrup (C++), 40 yrs of appliance computers

by cctalk＠snarc.net

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.
