NCR Century Series

NCR Century 8200

This smallest member of the NCR Century family bridges the gap between the NCR 399 and the NCR Century 75. It provides an ideal entry point for the first time EDP NCR Century 8200user or serves as a satellite unit to current large mainframe installations. The system is easy to understand and easy to operate, yet remarkably versatile. Despite its small physical size, it has the range and capacity to support multiprogramming and multiple online display terminals.

System Hardware


The NCR 8200 processor is a powerful, 16-bit word minicomputer with a full repertoire of arithmetic, logic, and data transfer commands.


Visual display terminals provide direct man/machine interface for rapid data entry and retrieval. Terminals have been specifically designed for ease of operation, with conveniently placed, typewriter-format keyboards comprising 64 upper-case alpha characters, digits, and symbols. A separate 10-key pad in standard calculator format simplifies entry of all-numeric data. Data is displayed as black characters against a white background with exceptional sharpness and definition. The terminal screen is 12 inches diagonally, and displays 24 lines of 80-character positions each.

Magnetic Tape

For those users who wish to employ magnetic tape for data storage, the NCR 8200 can accommodate a handler for 9-channel tape recorded at either 800 bpi (NRZ mode) or 1600 bpi (phase mode) density. Transfer rate is either 10 or 20 kilobytes per second, depending upon recording density.

Magnetic Disc

Single and dual flexible disc drives are available for those users who wish to employ this medium for data interchange. Each single-surface flexible disc stores up to 242944 bytes of information. Data transfer rate is 38 kilobytes per second with a maximum access time of one second.
