CDC 6400

CDC 6400

The CDC 6400, a member of the CDC 6000 series, was a mainframe computer made by Control Data Corporation in the 1960s. The central processing unit was architecturally compatible with the CDC 6600. In contrast to the 6600, the 6400 had a lower-performance CPU which processed a single instruction at a time. Memory, peripheral processor-based I/O, and peripherals were otherwise identical to the 6600.

The CDC 6500 was a dual CPU 6400. The CDC 6700 was also a dual CPU machine, but had one 6600 CPU and one 6400 CPU.
