Processeurs 36 bits
Certains ordinateurs étaient basés sur une architecture processeur 36 bits, dont notamment :
- Le DEC PDP-6, puis le modèle PDP-10
- Les IBM 701, 704, 709 (à lampes), puis 7090, 7094, 7094 II, 7040, 7044 (à transistors)
- Les GE (General Electric) GE-635 et GE645 ainsi que le Honeywell 6180
- Les UNIVAC 1106, 1107, 1108, 1110, 1100
- Les machines Lisp Symbolics
Le choix des 36 bits n'est pas un hasard : c'est pour garder une certaine compatibilité avec les calculateurs décimaux dont la précision étaient de 10 chiffres. Il faut 35 bits pour atteindre une précision équivalente en base 2. De plus, on peut facilement coder l'alphabet (A - Z, 0 - 9) sur 6 bits, et donc placer 6 signes dans 36 bits. Le code définissant les caractères codés sur 6 bits s'appelle SIXBIT.
