CP/M

CP/M (Control Program for Microcomputers) is an diskette based operating system originally developed for the Intel 8008 microprocessor development system but later modified to run on the Intel 8080 and was commonly used on Zilog Z80 based microcomputers, although there never was a version released that took advantage of the more advanced features of the Z80. It was written in PL/M and assembler.

The system was later ported to sundry microprocessor families including the Motorola 680x0, Intel 808x and the 80x8x, although it never gained the popularity there that it had on the x80 processors. It is also the basis for the TOS operating system used on the Atari ST line of computers.

History

CP/M-86 for the IBM Personal Computer Version 1.0 was released in April 1982. CP/M-86 for the IBM PC Version 1.1 was made available in March 1983.

Concurrent CP/M-86 operating system was announced in summer 1983.
