Kagan barn destroyed

by wdonzelli＠gmail.com

I am surprised this has not made list news yet. Claude Kagan had a terrible fire yesterday morning that completely destroyed his barn. The barn was fairly well known to many East coast collectors, as it was the home of the RESISTORS, a group of 1970s teenage hackers, as well as being the home of his collection of interesting technological items, including quite a few computers. Claude is unharmed and in decent spirits, and his house is unharmed, except for lack of electricity. The barn held many interesting machines over the years. Every so often Claude would let one go - sometimes to individuals, other times to museums. At the time of the fire, he still had some AT&T 3B2s, a Teletype 37, a Symbolics 3670, a more or less complete small town Central Office complex, and most importantly, the legendary Burroughs B205. Claude and I had just started to clean up the barn three weeks ago, and while I pulled out a good pile of very good documentation, much was lost. It is likely that there is little or nothing that can be saved. I made an emergency side trip today to help out, as I was down in New Jersey anyway. The destruction is total. The Burroughs is sticking out of the rubble, gutted and stripped of paint. The Burroughs is dead. -- Will

Reason to save very old computers

by evan＠snarc.net

Yesterday, here in New Jersey, a Burroughs B-205 tube computer was destroyed when the barn containing it burned down. It belonged to 85-year-old Claude Kagan who is a legend out here. Among other things, he formed the student computer club called the "RESISTORS" in the 1960s, and he wrote the SAM-76 programming language. The good news is that Claude was not harmed, and his main house is okay. But it's a good reminder, if anybody needs one, to save vintage computers while we can -- and to ensure the integrity of our storage areas.

Iomega

by jgessling＠yahoo.com

Despite their crappy products, IOmega did leave behind one good legacy. Cheap 5/12v DC regulated wall warts. Perfect for the VFD clocks that I'm working on. 5v for the logic and 12v for the display. And thanks to the throwaway nature of their products these can be found pretty cheap at local flea markets. Regards, Jim

I have a couple of 8-bit and 16-bit Bridgecards, but never ran across a Sidecar (and couldn't afford one when they were new, but didn't really need one then, anyway). I heard that by the A2000-A2286 era, one of the reasons Commodore kept making Bridgecards was for those customers whose employers had a strict "must run MS-DOS" rule for IT Purchasing. I do remember seeing forms in the mid-1980s with a checkbox that indicated if the machine being ordered was "IBM Compatible" - with the implication that you had better be prepared to explain yourself (or be rejected) if you didn't check the box. -ethan

HP Integral PC Manuals?

by derschjo＠msu.edu

Hey all -- Picked up an HP Integral PC. Probably paid too much for it but something about a luggable HP machine with a plasma display running HP-UX from ROM seemed irresistible. But I digress. Has anyone archived the manuals for this thing? I've been unable to find anything in my searches on the internet. Found some software archives (and after lubricating the floppy mechanism I've been able to make use of it...) but not much documentation. Docs for the HP BASIC for this machine would be nice, too. I've only played with it for a little while, but it seems like a really neat machine. (Though it seems like this thing is just begging for some sort of mass-storage other than the internal floppy and RAM. Anyone have an HPIB hard disk for sale? :) Thanks, Josh
