[comp.os.cpm] CP/M clarification

SAC.HQSAC-DOCT@E.ISI.EDU (John A. Wright) (10/25/87)

Can anyone answer the following questions:

1.  What is the difference between CP/M, CP/M-80, CP/M-86, CP/M+,
Concurrent CP/M-86, M/PM etc.  Specifically, what microprocessors
are used with each and whether or not any are compatible with any
others.

2. What is ZCPR2/3 and what is it used with/for.

3. What is "SMALL C" and how is it used.

Any help will be greatly appreciated.  I  will  be  in  the  CP/M
world  shortly with a 8088 microprocessor and need to know what I
have.
