SoftPC is a software emulator of x86 hardware. It was developed by Rod MacGregor, Henry Nash & Phil Bousfield, following the founding of Insignia Solutions in 1986 by MacGregor, with "about a dozen people who had left the CAD/CAM workstation specialist Computervision", believing in a market opportunity for an independent CAD/CAM consultancy. Originally a side project, SoftPC quickly became the main focus for the company, running PC software on workstations. Originally developed on SPARCstations, the first customer to license the software was Intergraph whose workstation had a proprietary processor architecture. Available originally on UNIX workstations to run MS-DOS, the software was ported to the Macintosh in 1987, and later gained the ability to run Microsoft Windows software. Besides Mac OS, supported platforms included SGI IRIX, Sun Solaris, HP-UX, IBM AIX, NeXTSTEP, Motorola 88000, OpenVMS on VAX and DEC Alpha systems, DEC ULTRIX, and others.
