CP/M Plus

CP/M Plus, also called CP/M 3, was the last 8 bit version of Digital Research's CP/M operating system, released in 1983 with its BDOS component designed by David K. Brown. It kept compatibility with existing CP/M 2.2 applications while adding new capability, most notably bank-switched memory management borrowed from MP/M, which let it use more than 64 kilobytes of memory on 8080 or Z80 based computers, a significant jump beyond the earlier version's limits. CP/M Plus also added optional file date-stamping and shipped with a relocating assembler and linker as part of its standard distribution.
