Apple III card q

[gbohling@herbie.unl.edu (Tiresias)]

Howdy,
I recently recieved an "apple III universal parallel printer interface"
<a380002> which I plan to use in my ///+. However, it has for its output
a set of pin-connections, much like a drive controller for the II, or
printer interface for the II.  But, it has a bout 4 fewer pins in the
central part of the connector than the extra ribbon cable I have from a
II printer interface.  These central pins <there are 20, 2 rows of 10>
are flanked by sets of 8 pins above and below, separated by a 1 pin wide
gap.
Does anyone know offhand what these pinouts are, and where they should
lead on a centronix connector?
