After reading lots of messages on the merits of using the 0xAxxx
***RESERVED*** instruction trap, I have to add my 2 cents. Using the 0xAXXX
or 0xFXXX traps is bad news. It limits compatibility with future 68000 family
products. Apple atleast avoided using the 0xFXXX trap which is why they have
had 68881 support for sometime while we still only have somewhat kludged,
semi-supported floating point support much less a 68020/68030 version of the
ST. If you want to have pointers for each routine, it wouldn't add many
instructions to use a legal trap and vector in software.
