HP DIO GPIO card 'options'

I've just boaght what appears to be a brand new HP 98622 GPIO card. This 
is the 16 bit parallel I/O card for the DIO bus, as is used on the 9836, etc

It came with a user manual. This was a lot more use than I expected it to 
be as it includes a schematic. It's a fairly thin manual, but full of 
information. One interesting diagram at the back shows the correspondence 
betweene the DIP switches on this card and the links in the 98032 I/O 
module for the 9825...

Anyway, it describes 4 'options' for this card. Each one was a particular 
cable -- one was the 50 pin Blue Ribbon plug to fit the card and bare 
wires on the other end. The other 3 were wired to connectors to fit the 
9885 disk drive (9" floppy), a Multiprogrammer (I forget the number, but 
the one that didn't have an HPIB interface) and finally one for the 9866 
printer.

The manual does give the switch settings to use the board with each of 
these devices, but no wirelists of the cables. And amazigly I have all 3 
of the listed peripherals.

So my question is obvious. Does anyone have any of these cables and could 
'buzz out' the wiring?
