I discuss CP/M emulators under MS-DOS, Windows, Linux in this section. Do a Web search for "CP/M emulator Windows" or ".Linux" or ".Mac" for more information.

(A few work with CP/M-68K on 68000 based computers.) 8080/8085/Z80 computers of the 1970's and 80's can be found check this part of my document about old and new CP/M computers.Ī popular option is to emulate CP/M-80 on their Windows or Linux system or Mac under an emulator. Or, they can run CP/M on an 8080 or Z80 emulator, typically on a older Windows/Intel PC. They can run CP/M on 8080 and Z80 based hardware (old systems or new). People who want to run CP/M today have several options.

If you want to compare them, download the docs and software and go right ahead! a comparison without some context or specifics is meaningless. And there is no "standard" for CP/M, just various versions of Digital Research operating systems, and various other OS's which offer some compatiblitiy to SOME of those versions. But only a few sites have listed all or even some of DRI OS's, or all the alternative OS's that have some kind of CP/M compatibility. Frankly, a Web search (or the links on this page) will lead to plenty of information. There is no simple answer to these questions. Were written specifically for Z80 based systems: they took advantage of Z80 instructions notĪvailable offered by the 8080-only programs from DRI.įrom time to time, someone asks some basic questions about CP/M like "what is standard CP/M?" or "what are alternatives to CP/M?" or "what is good or bad about CP/M?". But the CCP and BDOS could be separated and replaced with alternatives, in effect a new OS. Also, the BIOS was specific to each computerĭesign, and often users would construct their own BIOS versions. Later OS's from DRI had additional layers of softwareĪnd supported much more hardware and OS features: you'll have to read the docsĭRI's CP/M CCP and BDOS were distributed as binaries, assembled or compiled for the 8080 or 8086 processor. When a program finished, it would call the BDOS to reload the CCP, or reboot to reload the CCP, BDOS and BIOS. Programs would be called through the CCP, loaded in, and run by calling BDOS routines, some of which would call the BIOS to access specific hardware. BIOS is the custom I/O software for each computer model, which accepts calls from the BDOS to perform diskĪnd console and printer hardware access. The CCP is theĬommand-line processor with simple features like "dir", "type", and so forth. The operating system, responding to system calls from running programs.

More information is on my Digital Research Web page, and other pages on my Web site.Įarly versions of CP/M consist of an operating system or OS various tool programs for editing, assembling and debugging and sample source code files.ĬP/M's OS was divided into a BDOS, a CCP and a BIOS as separate programs.

This Web page provides some ideas about how to get and "run" CP/M today, or past alternatives to CP/M, in the 21st century.

See my DRI home page for links to Web pages about that event, and about about persons, companies and developments related to Digital Research and/or CP/M in the S-100 and microcomputer world of the 1970's. I worked on that through 2008 and updated my notes since. I decided then to describe that history on my Web site, before it was lost. Gary Kildall's operating system called CP/M was approaching 30 years old. To learn more about S-100 check my S-100 home page.Īs of year 2004, Dr. The first CP/M systems and many others were S-100 bus based systems. The Home page for all my Digital Research CP/M Web pages and information is at this link. Some links updated Mar 12 2021.Ĭontact and email information can be found in this notice.
