> Does anyone still have the PLANS for one? Yes but I'd build an imsai! The altair was first but not that nice technically. Also the case, front pannel and many componenets would have to be fabricated. I happen to have a spare case and power transformer. I'd love to get an imsai or 8800b box so I could fully retire(not sell) the altair I have. Allison

Altairs (was RE: Collector Article)

by kaikal＠MICROSOFT.com

I'm kind of curious how many Altairs we have on this list. I've got 3... I know that Jim has at least 2. Who else? | From: Marvin | Someone that | contacted me recently said that they had sold their Altair for $3000. Whom? | Another story I heard (true?, I don't know) was that someone advertised | their Altair on the net for $4000. This person was flamed for asking so | much, and his only comeback was that it had already sold. If this happened, it had to have been before 3/95, since there is no reference to it in DejaNews. | There was a | reference in TCJ by one of the editors(?) that they wouldn't be | surprised by the price reaching $10,000. I agree, though it's going to take a few years. People tend to acquire items that they wanted when they were in high school or college. Those people are now in their early forties, and that syndrome doesn't really get going full steam until 50-60 (my father, with 7 Corvettes, is a perfect example). I'd put the Altairs at $10K+ in 10 years. They sky's the limit in 20 years, maybe $100K (all in today's money of course). One reason for the expected price skyrocket is the number of people like me (and several others on this list) who acquire them and will never sell them, thus depleting the market. Kai

AIM65

by dastar＠crl.com

Ok, here's the deal. Marvin & I are both in contact with a guy who says he has 14 AIM65 units. Hopefully you all have been paying attention and have read the messages describing what this is. Marvin & I are of course both interested in buying one, and we dicussed the possibility that others in the discussion would be interested as well. We feel that if enough of us get together and offer this guy a bulk buy-out, we can get a good price from him. Marvin & I are talking about $20 a piece as of now. If this is of interest to anyone, I can give you his e-mail address and you can ask specific questions, but make sure you mention you are a part of this one-shot buyout so that we get a good deal. I think first we should get a count of who is all interested and then approach the guy. He's in New Jersey, and I don't think shipping should be more than $5 per unit. His e-mail address is Mikeooo1(a)aol.com and he left his phone number for me: (201) 331-1313. Please reply if you are interested in going in together on this.

1 GB SMD Disk drives

by kyrrin＠wizards.net

Those of you who own systems that use SMD drives, take note! RE-PC, Seattle, WA, has turned up a quantity (6 or 7) of Seagate 'Elite' series SMD disk drives. These are small ones (physically speaking), in the form of 5.25" full-height. They're brand new, still in their original boxes, and appear to be unused. I know these will go cheap, since SMD is useless to the PC world (thank God!). If these are of interest to you, either drop by RE-PC (if you're in the Seattle or nearby areas -- 1565 6th Ave. S, near the Kingdome), or give them a call at (206) 623-9151. Ask for Steve Hess or Mark Dabek, ask specifically about the Seagate SMD drives, tell them I sent you, and make them a decent offer.

Sam ------------------------------------------------------------------------------- Computer Historian, Programmer, Musician, Philosopher, Athlete, Writer, Jackass 02490420 60320 THE CUTTING EDGE A Byte of History Techies Taking a Scroll Down Memory Lane Los Angeles Times (LT) - MONDAY August 12, 1996 By: GREG MILLER; TIMES STAFF WRITER Edition: Home Edition Section: Business Page: 1 Pt. D Story Type: Main Story; Infobox Word Count: 1,797 TEXT: The nerds are getting nostalgic. Barely 20 years into the personal computer revolution, techies across the country are growing increasingly sentimental about the machines and programs that changed their lives and ushered in the Information Age. For them, booting up a vintage Commodore PET computer can conjure misty-eyed memories. Toggling the switches of an Altair 8800 is better than gripping the gearshift of a first car. And a shrink-wrapped copy of VisiCalc software beats a mint-condition Mickey Mantle baseball card any day. This is the memorabilia of the PC generation, and after spending much of the last decade or two collecting dust in suburban garages from Silicon Valley to Boston's Route 128, it's starting to make a comeback. Virtual museums of vintage hardware and software are sprouting up all over the Internet's World Wide Web, as are online classified ads placed by collectors desperate to reacquire the technological wonders of their youth. Some rare PCs are fetching much higher prices now than they did when they were brand-new, and even revered institutions such as the Smithsonian are bolstering their computer collections. "The amount of activity that I see is amazing," said Kip Crosby, president of the Computer History Assn. of California in Palo Alto. "People are always asking me: 'Can you find me an Altair? Can you find this or that?' I get 10 to 20 phone calls and e-mails a month, twice as many as a year ago." Most of these early machines and programs, which didn't work very well when they were new, are even more troublesome to maintain now--and have been rendered obsolete by wave after wave of new equipment. But like certain cars or baseball cards, high-tech relics are somehow enhanced by the passage of time. Collectors see them as the symbols of a more colorful computer age populated by legendary personalities who became billionaires--or, in some cases, went bust. "That's why I'm interested in computer history," said Co Ho, 30, an Internet administrator at Fullerton College. "Many people could have made it big, but they fell asleep and ended up having somebody else eating their cake." Ho collects vintage software, especially programs that changed the computing landscape but somehow faltered. One of his favorite pieces is CP/M, an early operating system created by Digital Research. CP/M might have become the operating system had Digital Research's founder, the late Gary Kildall, been more hospitable when IBM came calling to license his software. In a legendary blunder, Kildall and his wife refused to sign IBM's confidentiality agreement, and IBM executives took their business to a then-tiny company known as Microsoft. "CP/M missed the boat because of casual behavior," Ho said. "It's really a sad story." Ho is one of the few people who collect software. More collect hardware, and one of the most sought-after machines is the Altair 8800, introduced by MITS Inc. of Albuquerque in 1975. It didn't have a keyboard or a monitor, only rows of switches on the front of the box. The Altair kit sold for $395 when it was new, but one in good condition today can fetch as much as $1,500 because of the exalted position it holds in computer history. Widely regarded as the first mass-market personal computer, it launched a craze when it appeared on the cover of the January 1975 issue of Popular Electronics. Bill Gates even dropped out of Harvard to develop an early version of the Basic programming language for the Altair. The Altair "established Bill Gates in business," said Gwen Bell, founder of the Computer Museum, a Boston mecca for computer lovers. "One of our prize treasures is the original Basic tape that Bill Gates developed on the Altair." Collectors tend to pass over some of the most popular early machines, such as the original IBM PC and the 1984 Apple Macintosh, because there are just too many of them. Scarcity counts, which helps explain why the most valuable collectible is the Apple I. Introduced by Steven Jobs and Stephen Wozniak in 1976, the Apple I was nothing more than a circuit board. It had no keyboard, no monitor, not even a case. It sold for $666, and only a few hundred were produced. A well-preserved Apple I can fetch as much as $12,000 today, sometimes more. An Apple I signed by Jobs and Wozniak sold for $22,000 at a fund-raiser auction for the Computer Museum several months ago, Bell said. That kind of appreciation has attracted the attention of even non-techie collectors. "I got a call from an investment advisor for a Wall Street banker," Bell said. "He asked: 'Should I get him into collecting old computers? Will they increase in value more than art?' I said, 'I don't know--I'm not a dealer.' " In fact, there aren't any prominent dealers of antique computers, at least not yet. But a few collectors are hoping to change that, including David Greelish, founder of the Historical Computer Society in Jacksonville, Fla. Greelish, a computer repairman, has spent about $2,600 in recent years building a collection of 35 computers, mostly by trolling for bargains on the Internet. He uses search engines such as Yahoo to root out online classified ads for Altairs and other vintage machines, and he keeps an eye on alt.folklore.computers, a newsgroup where history buffs hang out. "Ultimately, I would like to see (the Historical Computer Society) grow and publish magazines and books," he said. "I'd like to start displaying our collection and even restoring computers for sale." Greelish and others said would-be collectors should look for machines that look clean, have all the original equipment and documentation and still run. A number of guidebooks are available, including Stan Veit's "History of the Personal Computer," published by WorldComm in Asheville, N.C., and "A Collector's Guide to Personal Computers and Pocket Calculators," published by Krause Publications in Iola, Wis. Experts urge caution, however. There's no guarantee that old computers will grow in value, and they are very difficult to maintain. "If you've never opened up your computer and looked inside, this is probably not the collectible for you," Bell said. Instead, experts say, this is a hobby better left to people who were enthralled by the recent PBS documentary "Triumph of the Nerds," people who still have a soft spot for monochrome terminals, "Chiclet" keyboards and the odd shapes of the early machines. But even among techies, there are plenty of people who scoff at this new fad, including Kim Nelson, service manager at ACP Superstore in Santa Ana. Founded 20 years ago, ACP is one of the oldest computer stores in Southern California, holds swap meets that attract legions of collectors, and might be one of the region's best unofficial museums. The store's top shelves are crammed with artifacts of computer history, although Nelson calls it junk. "Isn't it amazing that we have computer folklore now," he said, walking with a reporter along rows of vintage Commodores, Imsais and Tandys. "That's kind of sad when you think about it. Seems to me there are things that are a lot more important." But as he uttered those words, service technician John Krill walked by and surveyed the line of creaky machines. Almost against his will, Nelson was sucked into an episode of technology reverie. "Look at that Kaypro," Krill said. "That company grew so fast they were warehousing their inventory in tents." "Weren't they the ones that had the fire too?" asked Nelson, perking up just a bit and eager to demonstrate his techno-trivia prowess. The conversation drifted from machine to machine. "When I was in college, I would just leave my Osborne up in the library," Krill said with a laugh, recalling the immobility of the first portable computer. "The damned thing weighed 27 pounds. I didn't want to lug it around." Fifteen minutes passed before the two realized that their walk down memory lane might have strained the attention span of their guest. "That's enough, John," Nelson finally said with an embarrassed grin. "You're boring him."

Imsai 8080: Modeled on the Altair, the Imsai had several technological advances and a more polished look. Had no keyboard or monitor but was briefly the fastest-selling personal computer. Apple II: This is the machine that launched the company--and the personal computer industry. Apple II computers came with a keyboard, monitor and two disk drives. Most important, they ran VisiCalc, the original spreadsheet program that was the personal computer's "killer application." Osborne I: Considered the first portable computer, even though it weighed about 30 pounds and was the size of a suitcase. It had a 5-inch screen, two floppy disk drives and 64K of RAM.

Was the first computer to use variable speed disk drives Okay, I dug up where I got that idea from (ACM/Computer Museum Computer Bowl, 1994, Round 3, Toss up question #6): "6. The Victor 9000 computer featured an innovative design in its disk drives. What was unique about the disk drives?" and the answer was: "6. Variable speed" So in between reading that, and now, "innovative" transmogrified into "first of its kind". Sorry about that! >That's how it gets 21 sectors on tracks 1 to 17, 20 sectors on tracks 18 >to 24, 18 sectors on tracks 24 to 30, and 17 sectors on tracks 31 to 35. I thought the idea of variable speed drives was to have the same number/sized sectors on each track?

Digilog 1500

I seem I wonder if this is the same Digilog that made the Digilog 600 that is sitting in my office at work. It is not a general-purpose computer, but instead a serial line analyzer: one of those things that you plug in between two uncooperative serial communications devices to divine the nature of their uncooperativeness. It's also got a breakout box built in, and you can tell it's portable because it's got a handle (think Osborne 1 for some idea of its arm-lengthening properties, though). And a 3.5" stiffy drive for saving and replaying traces. I last used it in 1995, and have moved it along with me to different offices because no-one else wants it. It works well enough for what it is, but it doesn't understand IP, SLIP or PPP-in-HDLC at all. That is the sort of stuff we need to look at these days and we have better tools for doing that. -Frank McConnell

Has anyone who has their mini collection displayed on a web page put the *sound* of their machines on the net? I especially love the sound of those big fans and hard drives powering up. Whenever I get around to fixing up my 11/730, I'll definitely have to get a recording of it powering up: from the turn of the key, to the ratcheting sound of the TU58 microcode boot tape, to the sound of the LA-120 printing terminal printing the 'enter date and time' prompt. Actually, I don't have the LA-120, but remember the sounds. Clark Geisler Test Engineer Nortel

Here are the Tandy 600 specs

(That means I could hook up my 2" floppy, if I designed an interface cable, as it only has a 22-pin cable (all standard signals, plus power... just need to align the signals.) > One option ROM socket (accessible by removing > Multiplan) that holds BASIC or other ROMs >Power: > AC adapter, and built-in NiCd batteries AC adapter is 8V DC, 1.5A, IIRC.

(I'll have to look that one up in my '89 catalog...)

Apple ][e software?

by BROBSTONA＠wartburg.edu

>You do need the system disks in order to make copies of disks. Maybe. For the longest time, I didn't have a DOS 3.3 System Master for my IIGS. I thought DOS 3.3 was a neat OS because you could make your own bootable disks easily. (You can with ProDOS too, but I didn't know that at the time.) I managed to get DOS 3.3 by finding a game or something that ran on DOS 3.3, halting it with Control-C to get to the Applesoft BASIC prompt, then using the file commands such as INIT to make a new disk. I can't remember if DOS 3.3 has a built-in command that will copy a disk... There's probably a way to do it. -- Andy Brobston brobstona(a)wartburg.edu ***NEW URL BELOW*** http://www.wartburg.edu/people/docs/personalPages/BrobstonA/home.html My opinions do not necessarily reflect the opinions of Wartburg College as a whole.
