60-bit

From HandWiki

In computer architecture, 60-bit integers, memory addresses, or other data units are those that are 60 bits wide. Also, 60-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size.

Computers with 60-bit words include the CDC 6000 series, the CDC 7600, and some of the CDC Cyber series.
