Of course it all depends on the definition of a "computer". The list below encompasses many kinds of digital machines, including non- electronic and non-stored programmed devices. If we include the ABC, we may as well add Couffignal's computer, an electronic, parallel calculator programmed from an external disk. Developed in Paris in 1947-1950, it never went beyond lab experiments. Its only historical significance is its being a model of inept project management. We still keep the fossil at Musee des Arts & Metiers. But then the IBM 603 and 604 could even better qualify for the list? Best, Pierre Pierre Mounier-Kuhn CNRS & Univ.
