Version 0.2 of Z33RCP does not incorporate any far-reaching changes.  The
most significant one is a correction to the PORT command to make it work
properly with the HD64180 chip.  I had mistakenly assumed that the 64180 IN
and OUT instructions worked like the ones on the Z80.  They don't.  They
work like the ones on the 8080!  The new code uses the "IN R,(C)" and "OUT
(C),R" instructions.  The 'H' command was modified to work with CCP
implementations that have FCPENV enabled.  Previously, the address of the
FCP was hard-coded into the RCP.  I doubt very much that this ever caused a
problem, but it was not rigorous code before.  A minor bug in the 'WHL'
command was fixed also.

   I am going to be away on a trip for a month and wanted to get this out
before I left.  When I get back I hope to produce a proper ZCPR33-calibre
RCP, with interfaces to the error handler.
