Specialised software General business Advent Online Knowledge Advent Online Knowledge, Inc. was a Schaumburg, Illinois-based producer of software for Prime computers. Marc Software Marc Software International, Inc. of Palo Alto, California produced WordMARC word processing software for Prime computers. Computer Techniques (Queo) While Prime's PRIMOS operating system supported one or more compilers/interpreters for COBOL, FORTRAN, BASIC, RPG and 2 Assemblers, Queo was a step up: a procedural language more compact than COBOL, and with additional capabilities. It was offered by Computer Techniques, Inc. of Olyphant, Pa. Queo later was reimplemented for PCs. Office Automation System Prime acquired the OAS application from its developer, ACS America Inc., a now-defunct New York City software house. It competed in the UK DTI Office Automation Pilot, but did not win. OAS included electronic mail and word processing. Electronic mail use was initially restricted to a single minicomputer. Much later, Prime released email that worked with multiple Prime computers in a network, and a synchronised global directory system. Word processing was available either on dumb terminals like the PT25, PT45 and PST100, or on the partially intelligent PT65 terminal. The PT65 had to download the word processing software from the host minicomputer whenever the terminal was turned on. The terminal allowed the user to work on one page at a time, which was periodically saved to the minicomputer. This "intelligent workstation" concept for word processing was similar to the functions of popular systems from rival Wang Laboratories. Prime's intelligent workstation for word processing was faster because it used RS232C cabling runs instead of the coaxial links that Wang's systems used. Nonetheless, the word processing was not of the highest quality, and the PT65 was subject to software errors that scrambled the documents being worked on. OAS also had a bilingual language lookup feature, sometimes marketed as machine translation. Recognising the drawbacks of the downloadable WP workstation, Prime formed an agreement with Convergent Technologies for their AWS which
