60-bit computing

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, the CDC 7600, and the CDC Cyber 70 and 170 series.
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.
