- CDC 1700
The CDC 1700 was a 16-bit word
minicomputer, manufactured by the Control Data Corporationwith deliveries beginning in May, 1966. The 1700 used ones complementarithmetic and an ASCII-based character set, and supported memory write protection on an individual word basis. It had one general-purpose register and two indexing registers (one of which was implemented as a dedicated memory location). The instruction setwas fairly simple and supported seven storage addressing modes, including multilevel (chained) indirect addressing.
Available peripherals included teletypewriters, paper tape readers/punches,
punched cardreaders/punches, line printers, magnetic tapedrives, magnetic drums, fixed and removable magnetic disk drives, display terminals, communications controllers, Digigraphic display units, timers, etc. These interfaced to the processor using unbuffered interrupt-driven "A/Q" channels or buffered Direct Storage Access channels.
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-sharingoperating system.
The main operating systems for the 1700 were the Utility System, which usually took the form of several punched paper tapes (resident monitor plus utilities), a similar Operating System for larger configurations, and the Mass Storage Operating System (MSOS) for disk-based systems. A
Fortrancompiler was available. PASCALwas also available, via a cross compileron a CDC 6000 serieshost.
The 1700 series found use as communications concentrators, Digigraphics
workstations, remote batch job entry stations, and industrial process controllers. One application, running the AUTRAN program, controlled water and wastewater treatment plants for many years.
