RE: repairing/testing 82161a IL issue using 82162a
Hello dmh,

the only way to verify an HP-41-IL-System I know is to equip the HP-41 with an HP-IL Development Module (HP 00041-15043). With that module installed you can switch the HP-41 in so called "Scope"-mode and then monitor and display HP-IL messages as they go around the loop.

Simply switching the IL part from the printer to the cassette drive won't work in my opinion because the action for the different IL messages are device dependent. E.g. the Init message for the printer means position the print head whereas for the cassette drive it means rewind the tape among other things. For the video interface Init means position the cursor and clear the screen.

I know this doesn't sound encouraging, but it is definitely a surefire way to use the IL Development Module as an appropriate tool in this case.

Best regards

Karl
