IBM lance l’IBM 704 d\u00e9velopp\u00e9 par Gene Amdahl. Il s’agit de la premi\u00e8re machine commerciale disposant d’un coprocesseur math\u00e9matique. Puissance : 5 kFLOPS (milliers d’op\u00e9rations en virgule flottante par seconde). On consid\u00e8re souvent que cette machine marque le d\u00e9but de l’\u00e8re des super ordinateurs d\u00e9di\u00e9s au calcul scientifique. Elle utilisait une m\u00e9moire \u00e0 tores de ferrite de 32768 mots de 36 bits et allait 3 fois plus vite que l’IBM 701. Gr\u00e2ce aux tores de ferrite, cette machine \u00e9tait tr\u00e8s fiable (pour l’\u00e9poque) et ne tombait en panne qu’une fois par semaine \ud83d\ude42 C’est sur cette machine que sera d\u00e9velopp\u00e9 le langage FORTRAN.
