/CPM/ , n. [Control Program/Monitor; later retcon ned to Control Program for
|
|
|
|
|
Microcomputers] An early microcomputer OS written by hacker Gary Kildall for
|
|
|
|
|
8080- and Z80-based machines, very popular in the late 1970s but virtually
|
|
|
|
|
wiped out by MS-DOS after the release of the IBM PC in 1981. Legend has it
|
|
|
|
|
that Kildall's company blew its chance to write the OS for the IBM PC
|
|
|
|
|
because Kildall decided to spend a day IBM's reps wanted to meet with him
|
|
|
|
|
enjoying the perfect flying weather in his private plane (another variant
|
|
|
|
|
has it that Gary's wife was much more interested in packing her suitcases
|
|
|
|
|
for an upcoming vacation than in clinching a deal with IBM). Many of CP/M's
|
|
|
|
|
features and conventions strongly resemble those of early DEC operating
|
|
|
|
|
systems such as TOPS-10 , OS/8, RSTS, and RSX-11. See MS-DOS , operating
|
|
|
|
