The PIL-Box is the perfect interface solution for modern PC - which only support an USB port. The function test with the prototype I get from Jean-Francois is positive.
As Raymond explains the PIL-Box acts as gateway between your real HP-41 / HP-71 and HDRIVE1 of EMU41 / EMU71. Bidirectional transfer of programs, data and Ascii files is possible.
Not possible is the advanced control of external / real HP-IL devices by EMU41 / EMU71, actual for this applications you need the HP-IL/PC Interface Card.
When your PC supports a RS232 serial COM port you can use the HP-IL RS232 Interface for bidirectional transfer of data and programms (refer to IL2000 Interface System manual).
The software / hardware technology of the PIL-Box includes the needed plattform for future IL-devices, for example an IL-Massstorage Drive with simcard memory as replacement for the CMT-RAM-Disk. This device would be a really nice system extension for HP-41 + MLDL200 / NoVRAM / Clonix....
