CDC 1700

The CDC 1700 is a 16-bit word minicomputer, manufactured by the Control Data Corporation with deliveries beginning in May 1966.[1]

Over the years there were several versions. The original 1700 was constructed using air-cooled CDC 6600-like cordwood logic modules and core memory, although later models used different technology. The final models, called Cyber-18, added four general-purpose registers and a number of instructions to support a time-sharing operating system.[2]
