SubLOGIC

subLOGIC Corporation is an American software development company. It was formed in 1975 by Bruce Artwick while attending the University of Illinois at Urbana–Champaign, and incorporated in 1978 by Stu Moment. subLOGIC created the flight simulation program FS1 for the Apple II in 1980, followed by the more popular and widely ported Flight Simulator II in 1984, and Jet the next year.

In 1982, Flight Simulator was licensed to Microsoft, and through 2006 Microsoft released major updates to Microsoft Flight Simulator approximately every three years.

The company produced software other than flight simulators, including children's educational software, 3D graphics software for CP/M, the A2-3D1 animation library for the Apple II, the X-1 video card and 3D graphics software for the PC, and Night Mission Pinball (1982) which was originally for the Apple II and ported to the Atari 8-bit family, Commodore 64, and MS-DOS.

subLOGIC denouement
Bruce Artwick left subLOGIC to form the Bruce Artwick Organization, which was taken over by Microsoft and Tony Garcia in December 1995.

SubLOGIC continued under the ownership of Stu Moment, who produced Flight Assignment: A.T.P., which specialised in simulating passenger airliners. It used a scoring method to determine the performance of the user. SubLOGIC began a new flight simulator, but in late 1995 was acquired by Sierra, who completed the program and released it as Pro Pilot. Moment continues to run the present subLOGIC corporation as a generic simulation company, in addition to being an airshow display pilot with his Classic Airshow company.
