I recently interfaced my Amiga to a card that had an 8031 Microcontroller
on it through the parallel port as part of the final project in a lab course
I was taking.  Because my partner and I had already specified the protocol
(we were supposed to interface the card to one of the class computers, but were
lazy and didn't feel like fighting for one of the 5 available computers),
anyhow, I wrote my own parallel interface routines.  I used the OpenResource()
call and, like you, found no CloseResource().  I just commented out those lines
and pretended they were there.  I didn't have any problems re-openning the
resources later.  I never checked to see if that cost me memory.  I would bet
that OpenResource() is a "for-future-expansion" call.  Perhaps it would do
more when trying to allocate a resource on a PC-Card in the 2000?  I don't
know.
