[net.micro] Info wanted on multi-processor micro operations theory

Wilkinson@HI-MULTICS.ARPA (06/25/84)

 Anyone know of any good reference material/articles that discuss in
DETAIL the subject of multi-processor systems; both same board versions
(DEC Rainbow) and add on boards (like CPM board for apple).  I am
looking for info on how they usually relate to each other, how control
is transfered between them; what is the role of the secondary processor
(if any) when the alternate cpu is primary; are there many schemes or do
they all follow a pretty standard theory of operations; can you get REAL
concurrent user (vs i/o and housekeeping kinds of things) processing on
these systems (eg foreground/background).
 I sent Steve Ciarcia of BYTE a letter but a response in "Ask BYTE"
column will take awhile I expect.  Are there any other sources that I
might pose this very technical question?
 I ask this question as I have been looking at the Heath-100; The QX-10
with Titan 8088 board; and TRS80-16A.  If anyone has specific reference
info regarding any of these specific machines I would appreciate it.
