The CAB500 was a French transistor-based drum computer, designed at SEA around 1957[1]

It had an incremental compiler for a language, PAF (Programmation Automatique des Formules) similar to Fortran, designed by Dimitri Starynkevitch in 1957-1959. CAB 500's first model was delivered in February, 1961,[2] and more than a hundred examples were built. It had a magnetic drum memory of 16K words (of 32 bits) rotating at 3000RPM and could invert a square matrix of order 25 in half an hour.
