Oh, that's the HP-IL Development Module! I was referring to the HP-IL Diagnostic ROM above when I said it was never sold, which I still believe.

And looking at the 82166C Contents one can see the HP-IL Development ROM was included here as well.

I believe the "devel ROM" was a superset of the Diag ROM, which is likely how HP "productized" the earlier tool, originally intended for internal use.
