There is an interesting sentence in the publisher's blub for Bartik's book: "In 1946, Bartik headed up a team that modified the ENIAC into the first stored-program electronic computer." Nothing in any way controversial there... [Pause] .... except for 1) Post-conversion ENIAC did acquire the new control method introduced in the 1945 "First Draft of a Report on the EDVAC." Having looked at this conversion very closely, in association with my work on the topic with Mark Priestley and Crispin Rope, I'm probably more sympathetic to the general direction of the claim than most of you. However, that's also convinced me that "stored program computer" has been given too many different implicit definitions for that to be a prudent, or even meaningful, claim to make without at least attaching some kind of adjective to modify "stored program." (ENIAC essentially held instructions and data in an addressable manually erasable ROM while storing variables in a separate set of registers. It had other modern features including conditional branches and used indirect addressing so that the address acted on by an instruction could be modified at runtime). 2) The work took place in 1947 and 1948 rather than 1946. 3) Bartik played a role as a subcontractor but was not, by any stretch of the imagination, leading the effort. Those of you interested in learning more on this topic will enjoy our series of three forthcoming articles in Annals and our book in progress "ENIAC in Action: von Neumann, the Bomb, and the Programming Revolution." Meanwhile, I am curious to see how well the book itself aligns with the mass of archival sources on ENIAC. It will, in any event, provide some grist for one of our book chapters, "Remembering ENIAC."

SIGCIS'ers, Jean Bartik's autobiography is now available at http://tsup.truman.edu/item.asp?itemid=480. There is also an e-book version at Amazon. (I recently learned that Kindle books can be read through a browser or through an iOS/Android app -- you don't need a Kindle device.) Also: Does anyone know how the British Colossus computer got its name, other than the general assumption "because it was big"...? I emailed TNMOC about this. They wrote back and said they don't know and that nobody ever asked. _______________________________________________ This email is relayed from members@sigcis.org, the email discussion list of SHOT SIGCIS.
