Hi,
There are a LOT more documents about HP-IL that are available. The BEST source is one of the HP 82166C kits. It was a kit of parts intended for use in designing HP-IL into other devices. It contained most of the parts to built two HP-IL interfaces (HP 82166As) and ALL of the available HP-IL documentation along with a good supply of developer's tools such as HP-IL Development modules for the HP 41. I have one of the kits and here is a list of what's in it. I wrote list for something else so it's not formated for this page and it contains unrelated info.

Note: The manual says that kits assembled after the second quarter of 1983 should include 4 HP-IL hybrid networks P/N 1810-0651 instead of some of the separate components. I have one kit with separate components and another with the hybrid parts.
Note: The manual says that the microprocessors are included so that the builder has the option of building an interface which duplicates the function of the 82166A HP-IL Converter. Note, that although there are enough parts to build four interfaces, there are only two microprocessors and no cases or circuit boards.
