HP-71 Compu-LS module

[twa14]

Thanks for all your assistance and patience guys, I tried Christoph's method first, all went OK until the last step of "COPY:DOS" I get an "HPIL error unexpected message " on the physical 71B
The connection with ILper seems OK. When I turn the 71B on or off codes appear in the scope screen. The 71B main memory has 80,000 bytes, more than enough for the text file. I tried putting the dat file into the 9114B window but got an error message on the 71B "Invalid medium"
After various other attempts I changed your "COPY:DOS" to "COPY FOO:DOS" and that seems to be working, its still loading at the moment

Then I tried Dave's method. After starting HPDIR in the command prompt I can see the various options so I tick "initialize" in and get to the next series of options. I then tick in "Lif" to get to the next series. No more options appear (see attachment) so the last step "9122 MYLIF.lif" is "not recognized as internal or external command" so i could not complete but would like to know what I did wrong.
