I came across an article that said CP/M came out in
April 1974. I remember
using this OS in the microcomputer world in the late 70ās; early 80ās. It
came from PL/M, (Programming Language for Microcomputers) later renamed
CP/M(Control Program for Microcomputers). Iām not sure what its legacy is
though as far as I can recall it was wrapped up in litigation for quite
some time. It was used in the 8-bit world but not sure what it's role was
in the early PC world!
Happy computing,
