This is vintage for certain values of vintage, but I suppose this is as good a forum to ask as any. I suspect it's a little too new/esoteric for most people here, since it's really only about 5 years old, but it's right before the series went downhill, which is certainly a common enough topic of discussion around here. :-) I have two NIB (sealed) copies of Filemaker Pro 6, one for Windows and one for Mac. I additionally have one opened upgrade copy of Pro 7, but to my recollection it hasn't actually been used (because we didn't realize it was an upgrade before we opened the box). All should be 100% legal and ethical to use. Anyone want? Free to a good home. Pro 6 was a nice version of Filemaker, 7 maybe slightly less so. - Dave

Fujitsu Super-Eagle SMD-drive documents

by p.gebhardt＠ymail.com

Hi everybody, does anybody have documents related to the Super-Eagle drives made by Fujitsu (Model M2361A)? Documents for the predecesor (namely Eagle, M2351A) have been around for quite some time on bitsavers.org, but strangely, though the Super-Eagles are not that rare, no online-versions of its decuments are around. The Super-Eagle is different in certain aspects compared to the Eagle, so using the Eagle-documents is not a solution. One of my drives to be used with a PDP 11/24 via an Emulex-Controller turns off itself 2 seconds after turing it on and I'l like to find the reason for that some day. Documents are usually of great help here :) Kind regards, Pierre ? ------------------------------------------------------------------------------- Pierre's collection of classic computers : http://classic-computing.dyndns.org/

Arduino vs 555 reliability

by bob＠theadamsons.co.uk

> My expeirence is that more compelx ICs are noticably less reliable than > simple ones. That's much too simple analysis even if it were correct. Failure rates in ICs are primarily down to processing, packaging and handling (and to a lesser extent die area), not complexity. > > I would think the 555 had a much better lifetime than any > microcontrolelr > therefore. You would be wrong however. Today's ICs have a much better lifetime. Statistically today's commercial grade ICs have a significantly better lifetime than military grade ICs of the 555 era. > > The origianl 555 (as opposed to the 7555, etc) is large-ish junciton > bipolar and thus less likely to suffer static damage than a MOS > microcotnroller.

You could be telling me anything. > > -tony Now this is getting silly. There is no point in trying to say that what Tony is seeing is wrong: unless he is psychotic he is actually observing something that really has happened to him. And all that "I have this fancy job in industry and I have signed lots of NDAs, so I am important, while Tony is just a geek living with his parents" is a) rude and patronising and b) hiding behind these NDAs you claim to have signed. So go out and find publically available research reports or whatever on the Internet to prove your point, instead of trying to impress us with smoke and mirrors. However I think <unknown> is probably right in one respect about modern computers being more reliable: considering the complexity of a modern $500 PC, it is probably much more reliable than anything made in the '70s *at a corresponding price for the period*, i e today's cheap junk is more reliable thatn cheap junk from the '70s and '80s. OTOH Tony is also right that old computers were/are at least as reliable: they were better made than today's cheap junk. /Jonas

Prototype PCBs?

They are not the cheapest, but they are very good. The match your board characteristics with the best shop in China to make it. I've never had a bad board from them, and I have done everything from two-layer boards smaller than a postage stamp to 6-layer boards the size of a full sheet of paper. If you order 4 or less they don't charge you for the testing. Jon

Less than 2 weeks until VCF East!

by evan＠snarc.net

Hellooooooooooooooo world. Vintage Computer Festival East 8.0 is less than two weeks from now: it happens on May 5-6, 2012, at the InfoAge Science Center (2201 Marconi Rd., Wall, New Jersey, USA.) This year's VCF East will be the biggest ever. As of last weekend, we're up to six lectures, eight technical workshops (the newest being an all-weekend, kid-friendly "learn to solder" class), and two dozen hands-on exhibits. You'll also find our book sale, consignment sale, lunch, museum tours, prizes, and more. This year's lectures are highlighted by keynotes at 12:30 each day. Saturday's keynote is Dr. Thomas Kurtz, who co-invented the BASIC programming language. Sunday's keynote is Daniel Kottke, who was Steve Jobs' college buddy, India travel companion, Apple 1 board debugger, and Apple II, III, and Macintosh engineer. We are thrilled that Kurtz and Kottke accepted our invitations! Admission to VCF East 8.0 is very inexpensive. Adult tickets are just $10 per day and $15 for the whole weekend. Anyone 17 and younger are admitted free. Tickets are sold at the door. Directions, lodging, and related details are also on the VCF web site at http://www.vintage.org/2012/east/ and be sure to 'like' us at http://www.facebook.com/vcfeast8. All questions, such as admission, how to exhibit, how to become a VCF sponsor or vendor, etc., as well as any other questions from the public and from media, should be addressed to event producer Evan Koblentz -- evan at snarc.net, or call him at (646) 546-9999. Proceeds from the VCF East 8.0 benefit the InfoAge center, which is a grassroots, all-volunteer educational facility, and the MARCH user group (Mid-Atlantic Retro Computing Hobbyists). Thanks, and we hope to see you at the VCF East!

Looking for: Venix books

What I do have are the Venix/11 2.0 manual set as well as the base (root) distribution on 9-track tape.?? Unfortunately, the second distribution tape with the /usr filesystem has gone missing. Does anyone else on the planet have the Venix/11 2.0 tapes? Please let me know if you do. Cheers, -scott
