Copy Digital Cassettes?

[Sylvain Cote]

On the HP-75 you have the 00075-13015 Duplication & Privacy Solutions Book that allow you to clone cassettes.
The solutions book comes with two magnetic cards "MCOPY" and "INSTALL" that you have to load into the HP-75.
Those cards are inside the 00075-13015 Duplication & Privacy [soft tape] (sc).dat LIF volume.

On the HP-71 there is a MCOPYLEX file that should do the same as the HP-75 one.
The LEX is inside the lexfl1.dat LIF volume in Joe Horn Swap Files.

The third option would be to write a small BASIC program that read the cassette catalog into memory then copy the files one by one.
