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 16-bit microprocessor families including the Motorola 680x0 and Intel 8086/88 (CP/M-86), although it never gained the popularity there that it had on 8-bit processors. It is also the basis for the TOS operating system used on the Atari ST line of computers.
