on a PC at a fraction the cost per workstation of the "super mini" or SUN networks. Eventually only those users who used MEDUSA well beyond its 2D capabilities and had it well integrated into their manufacturing processes remained with Prime/CV. MEDUSA software continued to support the transition from “super minis” to remote workstations, and in the 1990s, the Unix workstations from Sun Microsystems were a popular option for the CAD package. Prime was divided into the two main divisions: Prime Hardware, which was responsible for the proprietary computer hardware, and Prime Computervision, which was responsible for the CAD/CAM business with MEDUSA and CADDS. Rebranded Computervision product: 1992 till 1998 With falling hardware sales Prime eventually stopped production of PrimOS computers and transferred its maintenance obligations to another company, thus being able to concentrate on the CAD/CAM software business. The company was renamed from Prime Computervision to Computervision (CV). Computervision’s main research and development centre for MEDUSA was at Harston Mill near Cambridge, where many of the development staff had been working on the software since the CIS days. When the company retrenched and moved its operations to Boston, USA in 1994, much of the programming was moved to India, so five former CV staff members with many decades of MEDUSA experience between them formed the software development company Quintic Ltd in Cambridge, which continued to provide MEDUSA development services to CV, and consultancy and customisation services to MEDUSA customers in the UK. PTC: 1998 till 2001 In 1998, CV was taken over by Parametric Technology Corporation (PTC). The development partnership with Quintic also transferred. After years of relative stagnation in the development of MEDUSA NG (Next Generation), there was a new push to launch the new release. MEDUSA NG was the first release to move from tablet-driven design to an icon tray and menu-based graphical user interface; but at that time it was still possible to use the tablet with MEDUSA. Under PTC's auspices, a new project, code-named "Pegasus" was launched. This was to develop a 2D drafting companion for Pro/ENGINEER based on the MEDUSA technology. CAD Schroer: 2001 till date In 2001, PTC sold all rights to the MEDUSA software to CAD Schroer, MEDUSA's biggest reseller in Germany. CAD Schroer, which started as a drafting bureau in 1986, was an active MEDUSA user and had developed a number of add-ons for the software. Thus MEDUSA was now owned
