BOS is gone, DOS has evolved into z/VSE and OS has evolved into z/OS. The DOS-11 operating system for DEC PDP-11 minicomputers. CP/M was a disk operating system--even though it was not named as such--used as the main or alternate operating system for numerous microcomputers of the 1970s and 1980s. TRSDOS was the operating system for the TRS-80 line of computers from Tandy. MS-DOS for IBM PC compatibles with Intel x86 CPUs.

Initial version, released in 1984, was nothing but MS-DOS 1.0 ported to Z80; but in 1988 it evolved to version 2, offering facilities such as subdirectories, memory management and environment strings.

Various compatible systems were later produced by different organizations, starting with DR-DOS in 1988. ==See also== Live CD ==References== ==Notes== Disk operating systems
It started as 86-DOS, which was modeled on CP/M, and then itself served as the basis for Microsoft's MS-DOS, and was rebranded by IBM as IBM PC DOS until 1993.
