How to make this working? can I receive a recipe prior the meeting?
a) EPRMCOPY is a BASIC program to be found where?
b) when an unknown module is connected in the front, how to dump its content? in an ILPER window? how? (probably its start and end-address must be identified.. how? then a command has to include these parameters)
c) when the content is dumped, how to see a readable content? ie how to transform the HEX from the dump in the BASIC commands or ASM mnemonics?
I would like to avoid such discussions in Stuttgart (in case the specialists are not there) but try to achieve straight a readable version of a ROM content.

a) EPRMCOPY is a LEX file, like ROMCOPY. CLONE is a BASIC program for copying EPROMs. EPRMCOPY can be found in the HP-71B Compendium.

b) The method that produces an exact copy is to use the DUMP routine.
c) The ASCII dump is copied to a text file and converted to binary using DMP2BIN. The dump can then be verified using TITANCHK if it's a ROM image. See the Emu71 manual.
