BA11-F boxer muffin fan source ?

by luc＠e2t.be

Hi, I had to look up a few words of your reply in the dictonary... You can (or could) do that for your own equipment, but I can't imagine me walking around with grease tubes and mineral spirits in the computer rooms of those days. Second, a fan costed about $10-$15 and a computer engineer about $80-$100 per hour. Third, you could't take the risk - if the bloody thing went down again the next 12 months, you smoked a huge cuban havana... and at last, this things are supposed to be impedance protected, but after being stalled for some time, more then once the windings were damaged... this was perhaps less common on the 110V versions, but our european 220V's had other behaviors. This was not ebay stuff you bought for a few bucks, but $80.000 - $100.000 equipment.

I thought that only clueless biz'driods and related idiots replaced perfectly good repairable equipment. All that one needs to do is disassemble the fans, clean them up, soak the old bearings/race assembly in mineral spirits, apply new grease and then reassemble the fans. -- Copyright (C) 2003 R. D.

Cambridge (the UK one! :) computer companies

by julesrichardsonuk＠yahoo.co.uk

Hi all, I do occasional volunteer work for a technology museum in Cambridge - one of the things they're interested in doing (once some new storage is put in so that things can be moved around) is putting on an exhibit showing the history of computing in the Cambridge area. At present I'm really after suggestions of machines to look out for (and machines themselves if it's that or they go to the tip!) - other than Acorn, Sinclair and Torch from personal experience I'm not sure who was really active in this region, and know basically nothing of what went on in the 60's and 70's around here. I expect some of you UK guys know the history of the British computing scene pretty well though. I already have plenty of Sinclair and Acorn machines (I picked up yet another BBC Master along with a more modern A3020 and Risc PC only yesterday) but will have to be on the lookout for other systems of local significance over the coming weeks. cheers Jules ________________________________________________________________________ Want to chat instantly with your online friends?

Alpha Phase 2 Testers needed for Vintage Computer Marketplace

by vcf＠siconic.com

Hello Folks. We're entering Phase 2 of our Alpha testing of the new Vintage Computer Marketplace. It took us a little bit longer than anticipated to get the basic service rolling but everything is in place and running now. We need a few more testers to help exercise the basic functionality before we turn it up to Beta testing. If you're interested in helping to test out the service, please e-mail me directly. Thanks! -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

DEC RL02 anyone need one?

by aek＠spies.com

I've just uploaded technical manuals for the RL02 and RL11 to www.spies.com/aek/pdf/dec. The RL02 manual includes a description of the drive interface.

Restoration: how far should it go??

by dwightk.elvey＠amd.com

Hi Well, some would consider what I've done to be real bad while others might see the reason behind my actions. I have an Olivetti M20. This is one of the rare desk tops that was made with a Z8000 processor ( there were a couple of s-100 boards as well ). I wanted to be able to bring up CP/M-8000 on this machine. The problem was that it didn't have enough memory. They sold two versions of the memory boards, 32K and 128K. I didn't think I'd ever see any 128K boards ( most everyone I know that has one of these machines has the 32K boards ). I did the unforgivable. I modified the boards to use 64K chips instead of the 16K chips. This required some cuts and jumpers since the boards were almost the same ( power planes are different ). While I was reluctant to do these mods, I felt that bringing this software alive was more important than preserving the original condition of the machine. After all, it is the software that completes the computer. The hardware is just the means. So shot me. Dwight

by kapteynr＠cboe.com

I agree. The whole historical significance of classic computers is the way they inspired tinkerer's everywhere. When you see my Altair, with its maze of prototyped wire-wrap interfaces, the monitor made from a converted B&W TV set, and the homemade "light pen" -- it brings all of this history into perspective. Never mind the fact that I haven't dared to power it up in years :-) -Rob -----Original Message----- From: Vintage Computer Festival [mailto:vcf@siconic.com] Sent: Tuesday, June 17, 2003 12:48 PM To: cctalk(a)classiccmp.org Subject: RE: Restoration: how far should it go??

I don't see how the machine would be better represented in its "factory" condition than in the condition it was in when it was last used. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *

Mostly post-production testing. Every board had a mod level, and most mods were indeed cut tracks and hand soldered wires. We also had to test equipment that was returned from the customer for new mods to be applied. (so does that count as "aftermarket" or factory?) Rob

I would also add that if the modification was simply board-swapping or chip-swapping (e.g., an overdirve processor in a PC), then I think that it would be more permissable to undo the swap. On the other hand, in general, I would leave in place a soldered modification. Indeed, such a mod might have been factory original, as I have seen a number of main boards with cut traces and hand-soldered wires snaking over the board. There will be times when the collector can not tell if the mod was "factory" or "aftermarket". A greyer area is the following: I bought a Tan-case Osborne 1 early on. Later, I had it upgraded with the 52/80/104 column display option and double density disk controller. As a "collector", does one remove the upgrades and have an "original" O1 (and it was used in the original configuration for quite some time), or keep the mods and have a fuller representation of the product's lifetime? Personally, I would keep the mods.

Personally, I am undecided on this. > Sometimes I keep the modification (particularly if it's useful and > doesn't adversely affect the operation and repairabilty of the machine), > sometimes I remove it. If you are merely a collector (I like to consider myself an "archivist") I think the modification is part of the historical fabric of the machine, and changing it would alter that history. If you're just a hacker, and you intend to continue use of the machine, then any change you make becomes part of the historical fabric of that machine. It just depends on how you look at it. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org * Old computing resources for business and academia at www.VintageTech.com *
