Hi,
I'm trying to install a FPCP (Floating Point Co-processor) 68881 card
to a 68000 based kit. I made the card, but when I read the 68881 manual
I saw that I need some special protocol to comunicate the 68000 with
the co-processor.
I don't understand so very well that mechanism, the manual talks
about a trap routine that hands the protocol.
I have some MACROS to do some operations, but I think that this is
no so very efficient, because I have the protocol included in all the
MACROS.
Can anybody help me with that? I'm looking for the trap routine,
is there some public domain routines to use the co-processor? Can
anybody explain me the mechanism of the trap routine?
Suggestions are welcome!
Thank's in advance!
