Rebuilding Colossus
mclock writes "I've just been to a website claiming that the British Colossus was the first computer :
"As 1996 was the 50th anniversary of the switch-on of ENIAC I made sure that Colossus was rebuilt and working in Bletchley Park, just as it was in 1944. There has been a stunned silence from across the water!" See the excellent site for the full story on the rebuild of Colossus in 1996." We've done a couple pieces on ENIAC before, and recently had the declassfication of Colossus 2 info. Like I said in the earlier ENIAC piece, there's a lot of debate as to the first machine: The German's had Zuse, US with ENIAC, Britain with Colossus. Me, I'm going with the abacus.

Also in contention for the distinction of being the first digital computer is the Atanasoff-Berry Computer built at Iowa State University between 1939 and 1942 by John Vincent Atanasoff and Clifford Berry. Supposedly, Atanasoff conceived the plan of the machine drinking bourbon in a roadhouse bar somewhere in Illinois in 1937.
In 1973, after a lengthy court trial, a federal judge declared the Eckert-Mauchly (Eniac) patent invalid and named Atanasoff the inventor of the first digital computer. It should also be noted that it was the first digital computer to use dynamic RAM. Lots of good information on the ABC and many more links can be found here and also here. Photos and diagrams can be found here.
If one closely examines this period of history, they find that it is a time that is just chock full with all kinds of convergences between mathematics, physical science, engineering and materials technologies that make the digital computer almost inevitable. After all, this is a device that had been conceived of, at least in part, as early as the Victorian age and the birth of the industrial revolution. Really, it was just a matter of time before somebody produced a working model, and as so often happens many people took different paths to the same end.
