International PC Owners

IPCO was a user group for IBM PC owners, operating out of Pittsburgh, Pennsylvania and later Poland, Ohio, USA. The founders were two engineers and their wives, Jim and Cindy Cookinham and Steve and Windy Hart. The group's selection of software - which covered business, science, graphics, education, utilities and games - was put together from user contributions. For an annual membership due ($15 within the US, $20 for Canada and $45 worldwide, as of 1982), IPCO members were eligible to participate in the group's software exchange: submit a program to the IPCO catalog, and receive a diskette with 4 free programs of your choice. The catalog included 80 programs as of early 1983, and over 175 by July that same year; by mid-1984 the count had grown to over 300 programs (selling for $3 per program or $6 per disk), plus 20 compilation disks ($15 each). Other productions included the bimonthly "IPCO Info" newsletter, with information on PC hardware/software (including the emerging shareware/public domain arena), reader requests, tips, comments, and even gossip culled from BBS messages.

Interstel Corporation

Interstel Corporation was a company originally established as Cygnus by Trevor C. Sorensen. He had made a game for DEC computers called Starfleet in 1981 and the company was created to market Star Fleet I: The War Begins, an adaptation for home computers. Together with his partners the company was incorporated in 1986 to form Interstel Corporation and from then on the name Cygnus was no longer used. In the same year Interstel Corporation became an affiliated label of Electronic Arts. In 1988 one of Interstel's games, Empire: Wargame of the Century, was named as Computer Game of the Year by Computer Gaming World magazine. Star Fleet II: Krellan Commander was released in 1989. A hostile takeover bid forced Sorensen to sell his shares and leave Interstel in 1990, and the company ceased operation in 1992. Before that, many titles were released, developed in-house or by external teams. Sorensen's worked continued at Supernova Creations, a studio he co-founded in 1991.
