Looks like I have a 1A IL module (based on the serial number, just arrived and haven't plugged in as yet) so could you please expand on what the issue is and how I can workaround it? Can I use the FRAM71B to do this? I don't want to make any electrical modifications.

Will the PIL Box work at all or what doesn't work (I just checked your website and it mentions a different firmware version for the PIL Box but doesn't go into detail on the issue).

The issue of some (not all) HP-IL modules 1A is described in this document. A fix for a simple HP-71B / PIL-Box configuration can be enabled with a jumper inside the PIL-Box.

Note that, as I mentioned above, the problem can not be solved by overriding the HP-IL ROM with the ROM 1B using the FRAM71.
