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 transitioned to Unix.
Computervision was acquired by Parametric Technology Corporation in 1998.
