From Wikipedia: "CP/M is an operating system originally created for Intel 8080/85 and Zilog Z80 based microcomputers by Gary Kildall of Digital Research, Inc.. Initially confined to single tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations, and were migrated to 16-bit processors."
Here is a list of sites actually storing documents and software for the CP/M operating system...

MSX was the name of a standardized home computer architecture in the 1980s. It was a Microsoft-led attempt to create unified standards among hardware makers, conceived by one-time Microsoft Japan executive Kazuhiko Nishi. Despite Microsoft's involvement, MSX-based machines were seldom seen in the United States but were hugely popular in other markets. Eventually 5 million MSX-based units were sold world-wide.

A lot of systems were based on Z80 cpu. Many of them are still alive on the net... and on the real world.
