HP-71 Compu-LS module

[Dave Frederickson]

Hi Tom,

First ROMCOPY will need to be loaded into your 71. You will need either a PC running Windows XP or older with a floppy drive (not USB) or a PIL-Box. I recommend Jean-Francois' PIL-Box.

Once you have an image of the EPROM the protection can be removed. Removing the protection from a file in RAM is easy, but removing the protection from a file in ROM might be a little tricky.
