Has anyone disassembled the ROM for the HP48G/X? I am particularily
interested in the bootup code and at least major outlining of the
calculator functions in the ROM code. Has anyone developed custom
ROMs for the HP48?

Thanks,
Tom

There is one called shellOS in hpcalc.org. but it doesn't use the
built in rom. it is a 32kb archive to put in port1.
It works great, but has not many applications.

There is another called MKor metakernel that uses and expands the
built in rom.

Has anyone disassembled any parts of the HP48G series Rom. I am
looking for commented code as a result of someone already
disassembling and studying the resultant assemble code. Thanks,
Tom

Look for Voyager on hpcalc.org, Derek Nickel's amazing re-write of my
TA program from long ago...

There is the program called sad which is a disassembler with a database of
symbols and comments:

I once disassembled the whole hp48gx-rom but cannot find the file now.

cheers,

Hi Pete:

Thanks, but that doesn't seem to be listed on HPCALC anymore. I'll keep searching.

When I type voyager into the search at hpcalc.org, I get Voyager 1.07
in the results?
