I should point out there is a technical error in the Guardian. The Baby was the first Electronically Stored Program in what today we would call RAM. ENIAC had been configured in stored program mode earlier in the year and had run a program stored in the function switches, e.g. ROM a couple of months before baby. Despite the fact that when running stored programs ENIAC's parallel processing features were not available, it was exclusively in this mode from 1948 onwards. Note both machines are theoretically "Turing Complete" but having only 32 words of 32 bits the Baby was not of any practical use for a further 18 months whilst major surgery was carried out to add extra store and instructions to the machine leading the emergence of the Manchester MK1. > This raises the question, is there anyone still alive from those > first-generation > projects?

Whilst I am not sure that any of the designers are still alive, I am sure that there are perhaps one or two who physically worked on the machine still with us. > > BLS Dave
