Hi, Speaking of tubes, television variety or otherwise, does anyone know if there are any tube-based computers, large or small, still in existence? I saw parts of one a few years ago at the Computer History Museum in Silicon Valley but none that have approached a 'working' unit or sub-unit! Murray--

Tubes & Computers of Olden Days

by ceby2＠csc.com

I'm rather surprised this thread hasn't brought up what has to be the most complete, working order, and fully programmable of the remaining tube machines. There are a couple of interesting systems in the process of restoration, but for my money, the best of the running examples is the Science Museum's (London's) Ferranti Pegasus. Unlike the Collosus replica, this is an actual relic, and recognizably a programmable computer in the modern sense. The Colossus and most of the later small systems are pegboard programmed and therefore cannot alter their instructions in flight. That Ferranti is demo'd regularly (though I never seem to be around on the right day). I'm sure everyone can do their own Googling, but it a pretty complete setup. I keep a loving photo of it in my office cubicle. Thanks, Colin Eby Technical Architect NR Performance Engineering CSC

CDC disk packs

by wdonzelli＠gmail.com

Some of you know that I have been selling some CDC disk packs on Ebay - ones I pulled out of CyberResources. I have noticed lately that there are some others selling packs on Ebay - and they are using the text from my auctions. My packs are either from Cyber's replacement stock, or are clearly marked as crashed - the ones on Ebay are not. Consider these other packs from these sneaky vendors as VERY QUESTIONABLE. My Ebay name is TOOBER. Currently I have no packs on auction. -- Will

by IanK＠vulcan.com

FYI: the Living Computer Museum presentation will be a joint one, including my colleague Rich Alderson. Rich has been an active member of the 36-bit community for many years. -- Ian ________________________________________ From: cctalk-bounces at classiccmp.org [cctalk-bounces at classiccmp.org] On Behalf Of Rob Jarratt [robert.jarratt at ntlworld.com] Sent: Saturday, February 20, 2010 11:27 AM To: 'General Discussion: On-Topic and Off-Topic Posts' Subject: DEC Legacy Event, Windermere, UK, 17th-18th April I am sending the message below on behalf of the organiser of this event, as he has been unable to resubscribe to the list: Greetings, I hope you don't mind me sending you an update on the DEC Legacy Event the weekend of 17th & 18th April this year.

(and repurpose it, as you have). -ethan --------- Check your local Dollar store; I just happen to have a couple of those 24 LED lamps in front of me at this very moment that cost $1.50 ea. (modding and putting them under the kitchen cabinets). Lots of neat stuff in Dollar stores; amazing that they can sell a solar powered/battery backed scientific calculator for $1.00 these days, esp. considering shipping and several middlemen also making a profit... Button cells 5/$1, $7 ea. at the Shack... etc.

Cross country hauling

by wdonzelli＠gmail.com

Again for 2010, I am crossing the country and am offering to pickup, haul, and deliver large items for list members. In mid/late April, I will be leaving New York, to arrive in California near the start of May, and I will be passing thru Chicago and Denver on the westbound trio, and likely Minneapolis on the eastbound. If business calls, I can hit other cities as well. I will have a van and a trailer, and can take fairly large items, like 6 foot racks. Weight is not much of an issue, with maybe a limit of 1200 pounds or so. Items hauled on my trailer are fully caccooned and tarped. Loading and unloading are included. I use the hauling to pay for my expenses on the trip (mostly fuel), so my rates are quite reasonable. Smaller items are welcome, of course. Some of my capacity is already taken for both the westbound and eastbound sections, but there is plenty of room for more. Also, from Denver to California I will be almost completely empty. Please inquire off list, please. -- Will

A huge amount of work was done by my fellow members of the Computer Conservation Society, including some of the people who designed Colossus in the first place and it is great to have it but Winston Churchill had the Colossi(?) broken up into small bits and so this is a replica, an extraordinarily correct replica but a replica all the same, therefore it is now running, not running again. Apparently they had less problems getting the difficult bits working as the plans had been released from UK government archives, than the off the shelf 'commercial' items, plans of which had long since been lost except for the odd hoarder like me and probably you. Also thing like switches were available off the shelf, with a high priority job they had first call on things and selected Spitfire fighter switches which were then being produced in good quantities and good quality.
