Abstract

The Interface Control System represents a technique for coupling virtually any small or special-purpose computer with commercially available terminals, paper-tape peripherals, and telecommunications lines (via MODEM) to remote large-scale time-sharing systems, for the purpose of more effective small computer software development and validation. The system provides the small processor with programmer aids typical of larger or more expensive computers.

Interface Control System

The Interface Control System represents a technique for coupling virtually any small or special-purpose computer with commercially available terminals, paper-tape peripherals, and telecommunications lines (via MODEM) to remote large-scale time-sharing systems, for the purpose of more effective small computer software development and validation. The system provides the small processor with programmer aids typical of larger or more expensive computers.

The figure is an interconnection diagram of the system. In this example, a small special-purpose computer 10 contains an operational program, to be validated. Conventional test units, including a System Signal Simulator 11 and a programmer console 12 are connected. The Interface Control System is implemented by loading the resident program in a spare area 13 of memory, and connecting a simple coupler to discrete computer inputs and outputs reserved for the purpose. A terminal 14 and a data set 15 are connected to coupler 16, the data set linking a remote large-scale time-sharing system for use in certain programmer options.

A wide range of capability may be programmed into the resident program. A typical program could include input and output of hexadecimal data and instructions via the typewriter. This would provide hard copy output of any block of memory. Program Halt and Snapdump capability would cause the operational program to halt at any instruction, by substituting a link to Interface...
