Are the A-line traps (illegal instructions with "opcodes" $Axxx) guaranteed to
be available for use through all 68xxx series processors?  I can't find in any
Motorola documentation any statement which says so either way.  The original
F-line traps from the 68000 are now used as coprocessor interface opcodes in
the 68020.  Does Motorola have the A-line traps reserved for some future
feature(s) also?

Please e-mail any response, as I don't regularly read this newsgroup.

Thanks,
