I am looking at the signal pathing of the block diagram.
it appears to "me" ( i use that term loosley). That the card cage is on the slow side 030 buss, from the PBX/Whitney, etc. its a bus, its all interconnected. A0 is A0, D0 is D0, etc, at least i think.
Now, if we can trace out which pins are what between the PBX/Whitney/Cage, you can make a Cage To Chip chart.
Then you can make a Chip to Dock connector chart on the duo.
Take the two charts, join them, then you get a Cage to Dock chart
and if the Dock pins are known, then you get a Cage To Signals chart, then you can adapt the cage to ANY 030 PDS buss.
