Bio/Description

Gary Kildall invented the first disk-based OS for microcomputers called CP/M, a pre-cursor to MS-DOS. CP/M became a fertile ground for development of application softwares for microcomputers that became pre-cursors to modern softwares in personal computers, including word processors like WordStar and database systems like dBase.
