A few things to know: To make 2 (or more) HPIL units communicate, one must be controller, and the other(s) are devices. HP41 and HP75 are always loop controller, HP71 can act as controller or device.
It's very easy to make 2 HP71 talk to each other:
just make RESET HPIL then RESTOREIO on the first one to take control of the loop, then you can do (for example): COPY anyfile TO :HP71 from the first one, and COPY :LOOP from the second one!
There is no easy way to make 2 HP41 talk to each other. You need either special complex software (using IL dev module for example), or 2 interfaces (GPIO, RS232) connected back to back.
In the case of one HP41 and one HP71, do CONTROL OFF on the HP71, then you can do OUTA on the 41, and ENTER :LOOP;A$ on the 71B (only an example!)
HP75 <-> HP71: it's similar to 41 <-> 71, just make 71 give control off.
