HP-42 ROM entry points ?

[G-SAN]

This was a very old question, but so far I have not seen any answer that really gives the answer the PO (or myself) seek.

For the HP48 and HP49 ROMs the list of entrypoints is known.

But I would like to know if there is such a list outside of the few people who actually know the HP42S (like Christoph Giesselink or Eric Rechlin for instance).

Second question: would it be illegal to start compiling an entrypoint list for the HP42S ROM if users study their own dumped ROMs and bring what they glean together in a shared document ?

I read that some entrypoints are common to the Saturn based calculators, and some are unique to a specific calculator. This can be seen in the entryppoint lists of 48/49, where part is common for both and part is unique to 48 or 49.

Any feedback would be most (really!) appreciated.
