Yes, that's what I've heard
too.

Yup. :-)

That is definitely true.

PL/M (Programming Language
for Microcomputers) is a port
of a language, it is not an
operating system. Some of
CP/M -- EDIT.COM and PIP.COM,
for example, was written in
PL/M, but the original MDS
BIOS and all versions of BDOS,
and CCP were written in 8080
assembler.
