摘要

The Anagraph system for which the software described herein was developed consists of a digital television display generator capable of supporting up to 16 users (user terminals consisting of standard television monitors and keyboards), an input device multiplexor, a programmable display controller, and a fixed-head disc for local data base storage. The RADC system is equipped with four of the possible 16 terminals. Optional system hardware is available, including a moving-head disc drive, an IBM-compatible magnetic tape drive, Diablo HyType printer for hard copy output (all of which are part of the RADC system), telecommunications interfaces, and a direct-channel interface to an IBM 360 or 370 computer. In addition to the standard keyboards, terminals may be equipped with extended keyboards which provide an extensive repertoire of programmed function keys, and with trackballs for direct graphical input (one terminal of the RADC system is equipped with a trackball).
