RE: HP41 Port to HP-IL Adapter
Hello Matthias,

Some statements that should clear things up:
  • Hewlett-Packard Interface Loop (HP-IL) is more or less the serial version of the Hewlett-Packard Interface Bus (HP-IB).
  • HP-41 peripherals are designed to use the HP-41 bus signals and can only be used with the HP-41.
    Some HP-41 specific peripherals:
    • HP-82104A Magnetic Card Reader
    • HP-82143A Thermal Printer
    • HP-82153A Optical Wand Bar Code Reader
    • HP-82160A HP-IL interface module (allows the HP-41 to communicate with HP-IL designed peripherals)
    • ...
  • HP-71 peripherals (card reader, HP-IL interface module, modules, etc.) are designed to use the HP-71 bus signals and can only be used with the HP-71.
    Some HP-71 specific peripherals:
    • HP-82400A Magnetic Card Reader
    • HP-82401A HP-IL interface module (allows the HP-71 to communicate with HP-IL designed peripherals)
    • ...
  • HP-IL peripherals (printers, tape drives, floppy drives, plotters, etc.) are designed to use the HP-IL interface signals (RX+/RX-, TX+/TX-) and can only be used with HP-IL equipped peripherals/computers.
    Some HP-IL specific peripherals:
    • HP-82161A Digital Cassette Drive
    • HP-82162A Thermal Printer (HP-IL version of the HP-82143A Thermal Printer)
    • HP-82163A Analog Video Interface
    • ...
So, in summary ...
  • HP-41 specific peripherals cannot be plugged nor used with HP-71. (the reverse is also true)
  • You need an HP-IL interface module for your calculator/computer to communicate with HP-IL peripherals
