Yes, I have returned. Lord Almighty, what a haul!! I can say with confidence that I definitely tested the maximum load specs for the (rented) Ford Windstar minivan. Every time I went over a good bump, the rear springs -almost- bottomed out. I'll be updating my web page soon with the gory details. Suffice to say I've got more than enough to keep me going, project-wise, well into next year. Among the more 'classic' items in the haul were a Kennedy 9100 tape drive installed in a nice 5-foot DEC rack, and a box full of 9-track tapes containing mostly DECUS RT-11 SIG libraries. Tony, I know you'll get a kick out of this. I also got hold of another 11/44 CPU box, loaded with cards (including a Unibus UDA50 disk controller). Between that one and my current unit, I should be able to get the power supply going AND fix the broken one for a spare! Since I'm not heavily into RT-11 (yet), I'd like to offer the RT-11 SIG tapes to whoever's interested and willing to pay shipping. There's about six or so, maybe a couple more. And would you believe I'm already planning next year's run? I know I'll see at least some of you at VCF in another couple of months. Until then...

hard drive data recovery

by allisonp＠world.std.com

< Alright for some :-). Alas most of us don't have access to a clean room. < Even if I was working at a place which had one, I can't believe they'd be < too happy if I wandered in with an HDA and started stripping it. Majorly true. I worked in pharmaceuticals and though they didn't use super clean rooms (class 10,000 worst case) the equipment was under a laminar airflow curtain with a flow of 100 linear feet per minute and the air under there was class 100. The air flow was obvious ly of the the machine then into the room where super clean was less important. < I would have thought looking for backscattered light would be more < sensitive and easier to set up. Still not sensitive enough for a clean < box, of course (in this form). The air flow and the sensing area cross section are important. Using a light source like a laser is helpful in getting the backscatter brighter. This is the problem of how many Angeles can dance on the end of a pin. You build a clean box and use a good HEPA filter. With 100-200cfm of incomming clean air once the dust in the box has been blown out it will be clean especially if gloved hands are the only thing inside. I'e heard a lot of "good luck", "it will not last" and "too dirty" from those that haven't. I've done it, when RD53s and 54s were in desperately short supply here and it does work without the clean box with some care. Obvious tricks like wearing nylon gloves to avoid finger prints, a canister of dry air to blow things off and keeping the unit covered when possible all reduce risk. Allison

hard drive data recovery

by allisonp＠world.std.com

< I'm not sure what that means, but I assume that the servo surface < contains a sort of coordinate system that the servo head reads and thus < guides the other heads. If that assumption is correct, why isn't it < possible to realign the thing with another servo platter? First it depends if the servo is embedded or dedicated platter or stepper (or other absolute positioner). For dedicated platter one head is assigned as the servo head and since they are all mechanically one assembly the rest just follow along. Now if a platter is changed it's data may be offset relative to the others. Same thing is true for replacing a head as the RELATIVE alignment between heads is disturbed. This case I believer the disk can be low level formatted and reused but existant data may be lost. If servo information does not exist (DeMIL'd drive) it's likely good for parts as servo tracks are hard to regenerate. If it's embedded servo per head each head as selected will follow the selected track servo signals and making relative head alignment less critical. If the servo is blown there is no way to regenerate easily. For cases of absolute positioners like older ST506/412/225/251 (and a swarm of others) drives getting alignment to cylinder 000 and beteeen heads would be critical for complete data recovery. If the drive is to be reformatted however a bulk erase and reformat will establish new tracks in some cases and make a mess in others. In the case of removable pack drives that is a totally different can of worms though simpler as they so have alignment procedures for field or depot use. Allison

IBM 3380 HDA

by Marty＠itgonline.com

Yes, dual head positioners on both sides plus four twenty pin connectors on both sides as well. David is correct as well, I have confirmed this HDA is from an IBM 4381 mainframe and uses a 3880 controller. Does this HDA have a lineage that goes back to the IBM Ramac? Any idea when this HDA was introduced? It certainly will make a great paper weight.

A short refresher on human psychology. Most of the time, a clearly thinking person does not do anything they consider wrong. Your spammer thinks he is doing someone a favor, and your songs are disrespectful teasing of his honest attempt to make money. Lawsuits are more effective because if he continues to do it, he'll lose all the money he made, maybe even go to jail. That said, keep up the good work :) >> Lawsuits appear to be the only effective weapon so far. > >I hope that 937 spam songs (at last count this morning) will bring some >manner of cheap and effective restitution. > > >Sam Alternate e-mail: dastar(a)siconic.com >------------------------------------------------------------------------------- >Ever onward. > > September 26 & 27...Vintage Computer Festival 2 > See http://www.siconic.com/vcf for details! > [Last web page update: 07/05/98] > > ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

Thats one thing I realy like about the German laws - spamming via any kind of personal device is forbidden - no fax-spam, no telex spam and no e-mail spam. Spaming is considered stealing your property, since the spammer uses your fax paper and your power line to print his message, and/or your time to check and delete spam. And theft is just unlawful :) After just 4 or 5 court ruleings spamming _IN_ Germany is almost zero - we just have SPAM from outside the country like senseless US-Spamm :) Gruss H. -- Ich denke, also bin ich, also gut HRK

MAD Computer

by jeff.kaneko＠ifrsys.com

I once had one of these nasty little beasties. In fact, it was a rare version that was badged for TELEX/Memorex. It used an 80186 CPU-- It was fast, at least to me, anyway (although I don't recall the clock speed). The Powersupply and floppy drives were in one unit, and the CPU was in another. It had a CGA compatible display adaptor. It also had what appeared to be an ISA bus, but most stock PeeCee cards would cause problems. I hacked this one by adding an 8-bit Hard disk controller, and disabling the HDC bios ROM. There was support for the HDC in the MAD-186 ROM, but the harddisk was not a standard option (AFAIK). I think this is the only computer I ever destroyed on purpose, and out of spite, no less. When we bought our 1st '286, my wife urged me to give the MAD to her brother. I really should have resisted, because the thing became a support nightmare. "Can I put a joystick on this?" "Uhh, whats an 'ERROR TRAP'?" "Uhh, RatRacer keeps locking up, can you fix this?" The computer got passed around the family, and I finally ended up with it about three years ago, when it was summarily smashed into little pieces-- retribution for countless sleepless nights when I had to play 'Tech Support'. I had been driven to the edge of MADness. Needless to say I wasn't into CLASSICS yet. I DID save the part with the PS and flopy disk drives, though . . .

Hmm, couldn't you be a bit more specific ? A few days in Germany is like saying 'visiting Alaska and BC and maybe some days on the West Coast' ... Oh Boy, Germany is more than 700 miles 'high' and up to 500 'wide' (nowadays:). Ok, for historic nerds there are at least 3 main places: - Museum fur Verkehr und Technik in Berlin - here you can find (beside a small display) a _complete_ replica of the Zuse Z1 computer - the first computer - and all mechanical :) - The Heinz Nixdorf Museum in Paderborn (a small city middle of nowhere) - They have a real comprehensive display. The single largest in Germany. A lot of small systems from the 70's - Of course since this museum started out as a company nuseum of Nixdorf. - The Deutsches Museum in Munich - THE science museum - I think #1 worldwide - the only thing coming close anyhwere might be the Smithonian Collections. A museum about almost anything. Also including a small Computer display - some 12,000 sqft. They have things like Zuse Z3 replika, Z22, Siemens 2002, PERM, IBM 360/20, TR4, Mark 1...realy impressiv. Althrough I think the modern part is a bit .. hmm .. lets say more like a junk yard - only a PC and a PET hidden in a sidecase and other random parts ... :( - They (the Deutsches Museum) opened a subsidary in Bonn some time ago (Kohl wanted to have such things in hs 'capitol' city :) - But this museum is nice, and well done, but more political/modern historical orientated - only 3 pices are special computer orientated: parts of a Z23 computer (afair the drum), some boxes of the SUPRENUM Project, and a 1 meg chip from VEB Forschungszentrum Mikroelektronik Dresden - the last East German high tech product - they almost ruined their industry - any research money available and a lot more was spend for this development. Beside these, maybe the RWTH in Aaachen (Aachen university) could be an interesting place - they have a small display of big old stuff ... Aachen, Bonn and Paderborn might be close enough to the westen border (Begique/Holland). Oh yes, and maybe send Stefan Walgenbach <walgen(a)do.isst.fhg.de> a mail - he is building the HCM (Home Computer Museum) in Oberhausen, thats just 60km east of the Dutch border. Maybe he invites you to see his collection of classic 80's small and home- computers - he has a big heap of european (English, French and German) home computers. Some hints about your planned tour would help. And if you come to Munich (Deutsches Museum) I would be glad to show you the museum, the city and bragg with my collection :) Servus H. -- Ich denke, also bin ich, also gut HRK

Painting Macs (was: fake next)

by peacock＠simconv.com

DEC actually tried something like that in the late 70's, they had an option for some kind of designer pattern painted on small racks going into office environments. I think it only lasted a few months, but I do remember getting the brochures from DEC (company was an OEM from DEC at the time). Response was underwhelming. Personally, if it isn't beige or blue I don't consider it a "real" computer. When DEC went to the black racks and purple lettering (hmm, early 70s?) that was too radical for me, I was glad to see a return to the traditional beige rack. DEC did have a nice desk with a builtin short rack, it was sold with PDP-8s used for small business office applications. It looked like a regular desk, but the left side was actually a 19" wide rack. It held a BA-11 and a dual 8" floppy box. For our customers that was more popular than the "designer" panels.

hard drive data recovery

What if this < deformed the platter? Head crashes are always bad. What generally happens for 5" and 3.5" winis is the head is ripped off the mount, slammed against the wall and shattered. the free arm gouges the platter badly. the metal dust from the grinding gets into the rest of the heads and it cascades. If shut down when the head first goes the platter will be shot. Repair would be trying to get head and arm assembly, another drive to get a good platter from. Then there is the problem of disassembleing the platter drive assy as many are "glued and screwed" and maintaining tolerances on assembly. Allison
