I remember hearing about undocumented opcodes in the mid 80's.  But I don't
think I heard the term "illegal opcodes" was used in the Commodore world back
then.  Perhaps what was called "undocumented" in the Commodore world was
called "illegal" in the Apple world?

Then, when the two worlds crossed paths via Usenet the difference between
illegal and undocumented became blurred.  I suppose we will get over it when
all the 8-bit processors die and go to silicon heaven.    :-)
