CP/M-86 was a version of the CP/M operating system for the Intel 8086. The commands are those of CP/M-80. It was later reworked to become MS-DOS compatible and renamed to DR-DOS and is discussed at more length in that article. ==Versions== A given version of CP/M-86 will have two version numbers. One applies to the whole system and is usually displayed at startup; the other applies to the BDOS Kernel (computer science). Versions known to exist include: * CP/M-86 for the IBM PC Version 1.0 (BDOS 2.2) - January 1982 - Initial release for the IBM PC. * CP/M-86 for the IBM Personal Computer Version 1.1 (BDOS 2.2) - March 1983 - Hard drive support was added. * Personal CP/M-86 Version 1.0 (BDOS 3.1) - November 1983 - Released for the Siemens AG PG685. Based on the multitasking Multiuser DOS kernel, it could run up to four tasks at once. * Personal CP/M-86 Version 3.1 (BDOS 3.3) - January 1985 - A version for the Apricot Computers Apricot F-Series computers. This version gained the ability to use MS-DOS formatted disks. * Personal CP/M-86 Version 2.0 (BDOS 4.1) - 1986 or later - Released for the Siemens PC16-20. This is the same BDOS used in DOS Plus. * Personal CP/M-86 Version 2.11 (BDOS 4.1) - 1986 or later - Released for the Siemens PG685. It is believed that the various Personal CP/M-86 versions were based on an unreleased product known as ''CP/M-86 Plus''; all known Personal CP/M-86 versions contain this string. ==External links== * [http://www.cpm.z80.de/ The Unofficial CP/M Website], which has a licence from the copyright holder to distribute original Digital Research software.

CP/M-86 was a version CP/M for the 8086. The commands are those of CP/M DR-DOS is a MS-DOS clone. Nobody knows if some source from CP/M-86 was reused in DR-DOS. : I can't easily reference this because my sources are so old, Ed. I almost certainly still have the old trade rags lying around in boxes out in the shed somewhere, but searching through trying to find the appropriate one and trying ''not'' to find a redback spider ain't on my list of nice things to do with a Saturday morning! Trust me: I was around at the time, and can assure you that DR-DOS was touted as a new product for marketing reasons but well recognised as a re-jigged development of CP/M-86, even by DR themselves. Look, for example, at the version numbers, or cast your mind back to some of the otherwise inexplicable error messages DR-DOS could throw up. User:Tannin : You may be right and this may be worth to be written in some article either CP/M, CP/M-86 or DR-DOS, but the article CP/M quote CP/M-86 while DR-DOS doesn't. And I think for the average user CP/M-86 is CP/M for intel 16-bit while DR-DOS is a MS-DOS clone. :User:Ericd : Sorry Eric, I don't quite follow you. The DR-DOS article already discusses CP/M-86 and it's later renaming to DR-DOS. I don't understand your statement "but the article CP/M quote CP/M-86 while DR-DOS doesn't". : When you say "for the average user CP/M-86 is CP/M for intel 16-bit while DR-DOS is a MS-DOS clone" you are undoubtedly right, but the fact that most computer users don't know anything much about operating systems (just as I am an average driver and I don't know anything much about the internal combustion engine or the development of anti-lock brakes) is no reason to repeat myths. (PS: I called you "Ed" before by mistake before. My apologies.) User:Tannin "but the article CP/M quote CP/M-86 while DR-DOS doesn't" having re-read the article I'm obviously wrong. I still disagree with you the chronology is : 1 CP/M 2 CP/M-86 3 DR-DOS If you want "the full story" you have to read 3 articles. If you connect CP/M-86 to DR-DOS you will have to go back to read about CP/M. I think that's unlogical. I'm not aigainst an article about CP/M-86. But the text I've removed confusing between CP/M and and CP/M-86. :User:Ericd Fine. User:Tannin
