    Yes

>2.  CP/M was written by DRI

    Well, some/much of the original work was done when he worked at/for intel
but he supposedly couldn't interest them in it so he left at some point to
continue development and marketing himself.

>3.  DRI is NOT related to DEC (Digital Equipment Corporation)

  It's not but CP/M is heavily influenced by certain aspects of the PDP
operating systems used on DEC's early minicomputers.
