PC DOS, also known as IBM PC DOS, is an operating system by Microsoft and IBM.
History
Seattle Computer Products released 86-DOS in August 1980. It was licensed and then purchased by Microsoft. The first versions of this operating system and its successors were heavily based on the CP/M operating system.
Microsoft licensed 86-DOS 1.10 to IBM, which released it as PC DOS 1.0 on August 12, 1981.
In 1982, Microsoft began releasing it as MS-DOS while IBM continued to release it as PC DOS. The first version to be published by both companies was PC DOS 1.10 which was the basis for MS-DOS 1.24.
PC DOS version 1.0 was released on August 12, 1981.
PC DOS 1.10 was the basis for MS-DOS 1.24, which were both released in 1982.
1983 saw MS-DOS 1.25, which was the basis for DOS distributions by manufacturers other than IBM. It was used as the basis for a DOS by Compaq as Compaq-DOS 1.12, by Texas Instruments as TI BOOT V. 1.13, by Zenith as Z-DOS 1.01 and 1.19. These were also alternately packaged as MS-DOS 1.01.
MS-DOS 2.0, which was also released in 1983, was completely rewritten from its predecessors.
