The format of the objects used in the HP28 were posted (and are in some
archives), and the HP48 formats are either the same or are similar.
I've been adding object disassembly to my disassembler that I wrote
(and posted) some months ago.  It understands about half of the formats
so far.  I haven't had a lot of time to work on it recently.  I can
disassemble commands into a 'USAG' like format, showing the arguments
required and the object that will be executed.  RPL commands are displayed
if referenced from other commands.  The other part handles disassembly
of machine code with tracking of nybbles that have been decoded.
