Mar 22, 2021 · CP/M was a text-based operating system created by American programmer Gary Kildall of Digital Research in 1974. Its initials stood for "Control Program/Monitor" at first, but Digital Research changed it to the more friendly "Control Program for Microcomputers" later.

The original CP/M is an operating system for 8-bit computers. It runs on either 8080 or Z80 processors in anything from 20k of RAM and can use a mixture of floppy and hard drives up to …

By 1977, CP/M had become the most popular operating system (OS) in the fledgling microcomputer (PC) industry. The largest Digital Research licensee of CP/M was a small company which had started life as Traf-0-Data, and is now known as Microsoft.

Jan 22, 2024 · CP/M is considered obsolete today - a single-user operating system that ran on what we see as limited hardware today. CP/M's adaptability, however, started a rich software ecosystem and prodded the industry towards hardware standardization.

CP/M (Control Program for Microcomputers) was the first commercial operating system to allow a microprocessor-based computer to interface to a disk drive storage unit. CP/M played an important role in stimulating the hobbyist personal computer movement of the 1970s.

Oct 1, 2018 · The CPM operating system (or CP/M operating system) was the first popular operating system for personal computers. Its rise and fall has been fairly well documented, if not well understood, and its author, Gary Kildall, is a tragic hero in the early history of computers.

Early versions of CP/M consist of an operating system or OS; various tool programs for editing, assembling and debugging; and sample source code files. CP/M's OS was divided into a BDOS, a CCP and a BIOS as separate programs. BDOS is the core of the operating system, responding to system calls from running programs..
