I have an olde OPUS card made to run Unix on old IBM's using an NSC
32032 co-processor.  It cam with 1 meg of memory on its card, plus a
daughter with another three megs.  This was the largest memory available
as a factory option evidently.  However, reading in the docs, I noticed
in "OPUS.CFG(4)", that it mentions a way to specify a different amount
of memory, in fact it uses 8 megs as the example, although it doesn't
bother to explain how to get the extra 4 megs (I'm assuming it takes
it from the computers onboard memory?).
Also, in the documentation to another similar card from another company,
also vending 4 megs max, it mentions the 32032 can address up to 8 megs.

So, I was wondering if anyone out there has done 8 megs on an OPUS.
If so, how is it done?  Does just setting the memory size in opus.cfg
automatically allocate 4 megs of system memory from the hostboard?

Nope, so sorry.  The memory for the Opus cards is whatever is attached
to the Opus card, and not from the AT-bus connected memory.  Juet before
they killed off the 32k based models, opus came out with a
daughter-board option to give 8 mbytes of memory to the series.  They
might have a few hanging around still.
