   Yes, it's a ROM for the 41. It's a very good ROM and usefull even if
you don't have any HP-IL stuff.

   Yes, exactly. It shows the description of all the parts in the kit and
has the schematics of the 82166 convertor. It has more but I can't find my
copy at the moment.

  The operating manual for the 82166.

>> p/n 82165-90012, Oct 1982

   The operating manual for the 82165. The 82165 is similar to the 82166 (
IL to 16 bit parallel buss) but the 82165 is bigger and runs from a HP
82159 wall wart that provides 8 VAC power. The 82166 requires 5 VDC.

    Yeap, except they have 16 I/O lines and a couple of handshaking lines.
The 16 I/O lines can be software configured as input only, output only or
input & output. They can be software configured as one 16 bit port, two
8-bit ports, etc.
