Last update for this thread, my discussions w/bbraun abut the addressing issues of both of these I/O hacks are over in the main SuperIIsiHack™ AKA SE/30's BANE . . . thread

I've switched to a more aggressive hack of the IIsi MoBo by substituting the original soldertail PDS socket with a Wire-Wrap Socket that will join the Hacked SuperMac adapter to the Hacked SuperIIsi's Mobo permanently for the Basement PDS Card Hack. I've decided that going half-way using the "Machine Pin Hack" would be reversible, but less robust physically and therefor less reliable electrically.
The same holds true for the marginally less risky, but equally aggressive, removal of the NuBus Connector from my spare NuBus Adapter. The cut down Gemini Card (DuoDock Donation) will have its Male NuBus Connector replaced with a soldertail version as well, after this is fully tested in the unmodified NuBus Adapter's Slot, the NuBus Slot will be removed and the extra length pins on the wire wrap connector will be permanently soldered to the NuBus Adapter slot's pads.
Please let me know if this diagram is self-explanatory.
Do I need to show the NuBus Slot Hack alone for simplicity or is the combo graphic sufficient?
Might it be clearer with both posted individually?
