If it's any help. I'll include the wirelist of the cable to link the 9885
to the 98032 GPIO interface (for the HP98x5 machines). That at least
should give the pinout....

The 'wire' column gives the wire colour using the resistor colour code
(base colour, then first stripe, then second stripe). The 'DD50' column
is the connectr on the 9885. Ignore the 'jumpers' section -- that refers
to the configuration jumpers inside the 98032 interface.
