60-bit computing

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.

60 bit CDC 6600 introduced in 1964

Examples

Computers designed with 60-bit words are quite rare with Control Data Corporation (CDC) being perhaps one of the few or perhaps only manufacturer to use this size. Examples include the CDC 6000 series,[1] the CDC 7600, and the CDC Cyber 70 and 170 series.[2]

Emulator

Museum examples of 60-bit CDC machines exist. There also exists an emulator for the series which will simulate the CDC 60-bit machines on commodity hardware and operating systems.[2]

gollark: This is not potatOS. This is some random text.
gollark: By some definitions.
gollark: I already ran PotatOS through it.
gollark: With a few null bytes at the end because of how my encoder works.
gollark: Yes, exactly.
