I played around with the NuBus Adapter Diagram from the DevNote and wound up doing a major overhaul.
This diagram shows both the NuBus and Basement PDS hacks, both done by soldering Machine Pin strips to the soldertails of the Gemini Card and the IIsi PDS respectively. One of the two cards mentioned will have its Right Angle PDS Male Connector removed and replaced by Machine Pin Strips in their standard configuration as high reliability sockets on a PCB.

Lets see if this clears anything up! :
