Searching the forum and the web the past few days for things related to the HP 71B I found a way to type in LEX files. Very promising to me as I don't have other means of I/O on my 71B.
I understand I have to type the MAKELEX BASIC source code in the 71B, get a LIF file (i.e. LEXFL1.LIF), make a hex dump (with LIFUTIL) of the desired LEX file (i.e. RPNLEX) and type this hex data into the 71B by way of the MAKELEX program.
BUT - on my XP machine it seems, I'm not able to do the hex dump part with LIFUTIL (or any other program for that matter).
I would be pleased if someone could give me a step-by-step instruction or point me to a download of hex dumps ;-)
Thank you in advance!
EDIT: Well, I managed to get a hexdump of RPNLEX on a LINUX machine with lif_utils. But where do I get the checksums required by MAKELEX??? And what is the relevant part (minus header and trailer)?
