Hallo Jim,

I now understand that this card was meant to let people using 
IEEE/IEEE cables when having for example a CBM3032. On itself a 
great idea! (Working with the ZoomFloppy last days just narrowed my 
vision, I think)

Using it for a CBM3032 means you have to solder a connector at the 
edge side and the "device" IEEE connector. Soldering its counterpart 
and just using the edge connector as so wouldn't work with your PCB 
because the lines mirrored: the original pin 24 is now pin 13, 23 = 
14, etc. and you haven't wired pin 24, 23 and other. But that is the 
same for the other side!
Wiring all pins 1-to-1 would enable you to reverse the signals and 
thus enabling the card for both purposes.

But as I already mentioned, IMHO there will be hardly a demand for 
this "ZoomFloppy card".
