The user interface, in the industrial design field of human–machine interaction, is the space where interaction between humans and machines occurs. The goal of interaction between a human and a machine at the user interface is effective operation and control of the machine, and feedback from the...

IBM 2260
The text-only 960-character monochrome IBM 2260 cathode ray tube video display terminal plus computer keyboard was a 1964 predecessor to the more-powerful color text-and-graphics IBM 3270. The 2260 screen image was normally configured with 12 lines of 80 characters each, which corresponded to IBM...

This differed from Westi's primary competitor, DUCS

DUCS was one of two early local teleprocessing packages for IBM's DOS/VSE environment. DUCS was an acronym for Display Unit Control System.- The product :DUCS provided an interface and access method for programmers to 'talk' to monitors...

, which reversed that model in that it was a subroutine package that read from and wrote to monitors. While Westi was not as easy to program and use as DUCS, Westi (like CICS) handled task management.

In terms of speed, Westi fell between DUCS and the considerably more process-bound CICS.

Pittsburgh

Steve Robert O'Donnell wrote the original DOS 2260 package, which was distributed free of charge. Its popularity made Westinghouse realize Westi had potential as a commercial product. IBM Sole his original idea and used it to make profit. Some Time after that he created the company called Goal Systems.

WEMSSA, under the direction of Eric Lutaud, contracted with GOAL Systems and eventually developer Leigh Lundin (author of DUCS Remote) for development, which focused on adding remote teleprocessing

 in Avignon, France. The result was WestiTAM, a 4k bi-sync module, which the Florida group expressed an interest in.

In 1978, WEMSSA resumed relations with the Florida group and eventually the two merged, coming under the new director of WEMSSA in London, David Hazlewood. Westinghouse committed to remerging the product line, re-engineering new products under the direction of Dr. Ferguson and Leigh Lundin. However, part way into development, Westinghouse began to break up the division during the outsourcing
