Was Zuse's Z3 the First Programmable Computer?
Roland Piquepaille writes "Several years before the Colossus in the U.K. and the ENIAC in the U.S., the Z3, built by Konrad Zuse in 1941, was crunching numbers in Germany. In a short article, the Register reports on allegations that the Z3 was the first programmable computer. Based on a binary floating-point number and switching system, it had all the attributes of today's computers, such as a control block, a memory, and a calculator. But it didn't have the ability to store the program in the memory together with the data because the memory was too small. It had a 64-word memory of 22 bits each and was able to handle four additions per second and to do a multiplication in about five seconds. And it was pretty big: five meters long, two meters high, and 80 centimeters wide. It was destroyed during WWII, and later rebuilt in 1960/1961. You'll find more details, pictures and references in this analysis of this ancestor of modern computing. [Additional note: you can find other references to the Z3, Colossus and Eniac computers in this former Slashdot item, posted in October 2000.]"
What's the cosmic connection? Does SCO own the rights to Zuse's work? Stay tuned, same bat time, same bat channel!
