World's Oldest Intact Working Computer
- The Witch - at the [British] "National Museum of Computing" - from John Pokoski, Nov 21, 2012
- The Witch [different URL with much more info] was based on Dekatron counting tubes. When I was in England around 1958 I made a clock that was based on the 50 Hz power. It was based on Dekatron counting tubes. I did not know of it [Witch] when I made the clock. (My clock is in [my home at] Clarkston, Utah.) - from LaFarr Stuart. Nov 22, 2012
- Re-booting the Witch, on YouTube
Mid 1950s transistors, several dollars each, and not all that swift. The then current circuit card technology - If your cell phone was built this way, it would be way too slow, and fill your house, and more. The glass things are diodes.

Items specific to Computer History Museum - CHM in Mountain View, Ca.
- A Comprehensive Guide to "Visible Storage", the display at the Computer History Museum from about 1995 to 2003
- On-Line Video of Past CHM Events via YouTube
- Volunteer Information Exchange Cumulative Index, you may have to cut and paste the URLs
- Proposed equipment labels
- Example Tours of Visible Storage.
The area is called "Visible Storage" because it is not a museum ( insufficient labels, ... ).
Demonstrations of the 'Manchester Baby' ;-)) received Nov 6, 2009
Yes, We do have the 'Baby' computer, the first stored program computer in the world. It is usually demonstrated on Tuesdays by volunteers, including some of the guys who worked on the original 'Baby' project.
Unfortunately, next Tuesday will be the last time the 'Baby' is demonstrated for several months, and it won't be on display for a few months from the end of next week either, due to a major refurbishment project at MOSI.
From approximately next April it will be housed in much nicer surroundings as part of our up-coming 'Revolution Manchester' gallery.

"Don't throw nuthun away!!" -
- An all too "typical" tale
In one of my bouts with college, the newspaper mentioned there was a series of classes, for school teachers, to be held in the St. Paul (Minnesota) Library about computers. A "design engineer" would be presenting the ERA/RemingtonRand 1103A.
Typically, I showed up with out registering, me - a school teacher??, collected a notebook of blue prints of overviews and details - dropping the course when the next meeting was going to be trying your program on the machine - and you had to be registered to do that -
I kept that notebook until about 1980 when kids were leaving home and we were down sizing.
- If I had known anyone would eventually be interested, or a suitable repository available, such as the later Computer History Museum, I would have kept that "Holy Relic" ;-)) .
Mike Milgram just reminded me that many (computer) manuals can already be found on repositories such as bitsavers.org which has accessable PDF files for most manufacturers at http://www.bitsavers.org/pdf/. Look there to see if your manual(s) are present there.
- If present, well, the world has black and white access to them. Potentially you have different dates ...
- If not present, read Al Kossow's recommendations and requests on his website.
- And a "typical" e-mail exchange

Subject: hello, 604 units
Hello Ed, Very interseting site on the IBM 604. I graduated from an electronics school in Mpls in 1960. Our instruction back than on computers consisted of flip-flop circuits to learn basics. An interesting project was the Overbeck ring and an "electronic roulette wheel" using the 2-xxxx triggers - flip-flops. After I graduated from tech school I ended up in Seattle,WA. What luck, a local scrap yard had an old IBM 604 for sale. My roommate and I rented a trailer and hauled the cpu home and scrapped it out. Really big filament transformers for all those tubes.. I managed to save 1 of the racks full of flip-flops, and's or's etc. The rack still is in my storage shed.... My point... do you have any of the old modules ? Want a couple for your desk, or wall. When I pass I'm sure the kids will get a large dumpster...... I live in Seymour Cray's home town and they have a great Cray museum here. Perhaps this would also be a good home, I donnated a couple of the modules to them already, people there really didn't know what the solid state modules in todays world replaced.. Thanks again Ed...

and a response from Robert Garner
Thanks for your informative note to Ed.
Turns out that an older colleague of mine (Hans Coufal) at IBM Almaden Research (who's no longer with us), had reportedly collected much of a 604, apparently still in storage somewhere in L.A. Your collection of spare modules could come in handy some day if these 604 components gets donated to the say the Computer History Museum and some volunteers elect to restore it. (There are crazy folks around thinking of restoring a tube machine some day...). So don't throw anything away! There is reportedly a working IBM 604 at the "House of the History of IBM Data Processing" in Sindelfingen, Germany.)
p.s. Did you see our 1401 restoration project at the CHM?: http://ibm-1401.info/index.html
p.p.s. I am looking for 700-series style tube socket...
