Memory-resident Unix system?

[Greg Noel]

Is there a version of Unix that provides minimal functionality?  We would
like to hook an existing driver to an existing application program and get
it to run on a special-purpose board.  Essentially, we would like to use
just enough Unix-glue so that the driver has the functions it expects, and
the application sees enough of the "system calls" so that it is happy,
and eliminate the portion of Unix that would be unneeded.  (Unneeded would
be disk I/O (no disk), multiprogramming (only one process), pipes (only one
process), time of day (but might need interval timing), tty I/O (no terminals)
-- in fact, almost everything except access to the specific driver.)

Some of the management here have heard of a system called something like
"C Executive" that may be what we want.  Does anybody know who/what/where
this is?  Is this a possibility?

The traditional offer is made:  Please mail me the information and if there
is sufficient interest, I will post a summary.  Tks.

(For UUCP people: ncr-tp is a new site, reachable via sdcsvax.  It will be
formally announced soon.)
