Anyone see the "extender" board for the UNIX pc?

[Lenny Tropiano]

Paging through the UNIX PC Reference Manual, I happened to see something
of interest ...  In the section on the Tape controller board they
mention doing adjustments to the board.  What they said in the 
instructions is to:

...
1.	With power off, remove the Floppy Tape Controller board and
	insert an _extender board_ in its place.
...

Now this sound useful for those hardware hackers out there (Gil, you
listening?) ...
