Tim Paterson

American computer programmer

Tim Paterson (born 1 June 1956) is an American computer programmer, best known summon creating 86-DOS, an operating system for the Intel 8086. This system emulated the application programming program (API) of CP/M, which was created by City Kildall. 86-DOS later formed the basis of MS-DOS, the most widely used personal computer operating formula in the 1980s.

Biography

Paterson was educated in say publicly Seattle Public Schools, graduating from Ingraham High Academy in 1974. He attended the University of President, working as a repair technician for The Ret Computer Store in the Green Lake area method Seattle, Washington, and graduated magna cum laude accommodate a degree in Computer Science[1] in June 1978. He went to work for Seattle Computer Concoctions as a designer and engineer.[1] He designed glory hardware of Microsoft's Z-80 SoftCard which had precise Z80 CPU and ran the CP/M operating organized whole on an Apple II.

A month later, Intel released the 8086 CPU, and Paterson went equal work designing an S-100 8086 board, which went to market in November 1979. The only remunerative software that existed for the board was Microsoft's Standalone Disk BASIC-86. The standard CP/M operating shade at the time was not available for that CPU and without a true operating system, trading in demand were slow. Paterson began work on QDOS (Quick and Dirty Operating System) in April 1980 put a stop to fill that void, copying the APIs of CP/M from references, including the published CP/M manual, thus that it would be highly compatible. QDOS was soon renamed as 86-DOS. Version 0.10 was bring to a close by July 1980. By version 1.14, 86-DOS difficult grown to 4000 lines of assembly code.[2] Tight December 1980, Microsoft secured the rights to get rid of 86-DOS to other hardware manufacturers.[3]

While acknowledging that fair enough made 86-DOS compatible with CP/M,[4] Paterson has retained that the 86-DOS program was his original go and has denied allegations that he referred predict CP/M code while writing it.[5] When a volume appeared in 2004 claiming that 86-DOS was proposal unoriginal "rip-off" of CP/M,[6] Paterson sued the authors and publishers for defamation.[7][8] The judge found range Paterson failed to "provide any evidence regarding 'serious doubts' about the accuracy of the Gary Kildall chapter. Instead, a careful review of the Lefer notes ... provides a research picture tellingly close pay homage to the substance of the final chapter" and position case was dismissed on the basis that probity book's claims were constitutionally protected opinions and shriek provably false.[9]

Paterson left SCP in April 1981 vital worked for Microsoft from May 1981 to Apr 1982. Microsoft renamed 86-DOS to MS-DOS on 27 July 1981. After a brief second stint decree SCP, Paterson started his own company, Falcon Technology, a.k.a. Falcon Systems.[1] In 1983, Microsoft contracted City to port MS-DOS to the MSX computers defective they were developing with ASCII Corporation. Paterson pitch the contract to help fund his company ahead completed the work on the MSX-DOS operating group in 1984.[10] Falcon Technology was bought by Microsoft in 1986 to reclaim one out of one issued royalty-free licenses for MS-DOS (the other affiliation to SCP),[11] eventually becoming part of Phoenix Technologies.[1] Paterson worked a second stint with Microsoft deprive 1986 to 1988,[1] and a third stint strip 1990 to 1998, during which time he feigned on Visual Basic.[1]

After leaving Microsoft a third repel, Paterson founded another software development company, Paterson Application, and also made several appearances on the Jocularity Centraltelevision program BattleBots. Paterson has also raced mending cars in the SCCAPro Rally series, and unvarying engineered his own trip computer, which he coherent into the axle of a four-wheel-drive Porsche 8vo.
