Computervision

Computervision, Inc. (CV) was an early pioneer in Computer Aided Design and Manufacturing (CAD/CAM). Computervision was founded in 1969 by Marty Allen and Philippe Villers, and headquartered in Bedford, Massachusetts, United States. Its early products were built on a Data General Nova platform. Starting around 1975, Computervision built its own "CGP" (Computervision Graphics Processor) Nova-compatible 16-bit computers with added instructions optimized for graphics applications and using its own operating system known as Computervision Graphic Operating System (CGOS). In the 1980s, Computervision rewrote their code to operate on Unix.

Computervision was acquired by Parametric Technology Corporation in 1998.

Computervision's first product, CADDS-1, was aimed at the printed circuit board layout and 2-D drafting markets. CADDS stood for Computervison Automated Design and Drafting System. The CADDS-1 system featured a combination digitizer and plotter mounted on a large drafting table.

Integrated circuit layout was added with the CADDS-2 product, which had a dedicated operating system and a 16-bit graphic database. When this proved insufficient resolution for VLSI (very large scale integration), the company developed CADDS-2/VLSI in the late 1970s. CADDS-2/VLSI included a new operating system, a 32-bit database, and user expandability through a dedicated programming language called ICPL (integrated circuit programming language), which was a dialect of BASIC, based on an interpreter licensed from Fairchild Semiconductor. The original CADDS-2 ran on Data General Nova 1200 computers. CADDS-2/VLSI ran on Computervision's own hardware which were modified Data General Nova's and modified version of DG's operating systems.
