Someone was kind enough to send me a description of the 6303, which is
supposedly a Hitachi part that runs 6800 code and has some additional
instructions.  The description I got did not distinguish which
instructions are 6800-compatible and which are 6303 extensions, but it
was sufficient for me to add the 6303 to my disassembler.  Given a
description of the differences between the 6800 and the 6303, I could
easily make it do the 6800 as well (the infrastructure is all there,
but lacking such a description I can't do much with it).

To the nice person who sent me that - speak up if you want people to
know who you are.  *You* know who you are, and thank you in any case.

The FTPable copy has been udpated.
