Analog Museum (English version) This is Professor Bernd Ulmann's website. Bernd has written about analog computers, taught about analog computers and bullt analog computers. This is the place to go to learn about analog computers.[Bad Schwalbach, Germany]

(Sadly now Offline)  Old-Computers.com That darned dash between Old & Computers is sometimes hard to type...but's well worth the effort. This is the most comprehensive and useful vintage computer site on the web. Sadly, after several attacks by hackers it has been shut down...we hope temporarily!!

The London Science Museum Up on the 2nd floor is the greatest collection on the history of computing...including Charles Babbage's brain floating in a jar of formaldehyde. As of some point after 2000, The LSM decided to no longer display Babbage's brain. But you can still see the first Difference Engine #2 which took 17 years to build. Planning began in 1985 and the Engine was completed in 2002. Under the direction of Doron Swade, the Computing Curator, it was built on the second floor out where visitors could watch the progress. [London, UK]

The Computer History Museum Just south of San Francisco is the premier collection of computers in the USA. [San Jose, CA. USA]

The Digibarn A vast collection chock full of unusual and one-of-kind items. The collection itself is worth the drive (be careful of the section of the road that is literally falling into the valley below) but the icing on the cake is the beautiful Santa Cruz mountain setting and the very amiable host, Bruce Damer. I understand that the Digi-Barn building was getting a bit old so it was closed down. But Bruce's wonderful collection traveled across the country to be put on display as part of the System Source Computer Museum (see below). [San Jose, CA. USA]

System Source Museum One of the largest collections in the entire country, Bob Roswell's collection is breath-taking. The items are beautifully displayed and, if you are lucky, you can get a tour by Bob. [Balimore, MD. USA]

EWI Study Collectioin Part of the Delft Universiy of Technology, this collection houses an ESIAC...the only other one that is know to exist. (The other ESIAC is in our collection along with documentation that indicates it was the inventors computer.) The Delft University group have an excellent in-depth paper describing how their ESIAC works. [Delft, NL]

(Sadly now Closed)  Analog Computer Museum & History Center Doug Coward's website is a treasure-trove of information on analog computers. And Doug is a very helpful and very nice guy!! It looks like Doug has closed down his website. That is a loss. [Texas, USA]

The Colossus Rebuild Located in Bletchley Park, this was a project lead by Tony Sales and many knowledgeable volunteers who rebuilt a Colossus computer. [Milton Keynes, UK]

The National Museum of Computing Located in Bletchley Park, this is now the location of the UK national museum. When I first visited here it was a small group of computer enthusiasts known as the Retrobeep Club. The entrance used to be through a nice fenced gate on Witton Ave. I bought one of my early computers from a member of the Retrobeep Club years ago and I toured some of the huts (which were in bad shape) where computers were just stacked up on one another, waiting for a club member to begin working on them. [Milton Keynes, UK]

IMSAI Computer Todd Fischer's website is packed with information about one of the pioneer companies in personal computing and includes information on his IMSAI 8080 that starred in the movie "Wargames". Todd built the first computer controlled house in the world...the IMSAI Dollhouse. [Online. CA, USA]

Computer Museum at University of Amsterdam This collection has a litle bit of everything from personal computers to very early analog computers. Of special note is the Beckman "Electronic Analog and Simulation Equipment" (EASE) computer! [Amsterdam, NL]

Hagley Museum It is not a computer museum BUT it does have some early computer museum documents from the Hollerith family (I know because I delivered a donation from Richard Hollerith) AND they have a magnificent collection of early technology patent models...truly amazing. And for those of you who don't like being indoors, they have acres of land along a beautiful river filled with even more technology. I used to bring students from the university here on a Saturday for extra credit and have a picnic lunch. [Wilmington, DE, USA]
