The docs say that design of a card for the Portable's PDS requires an auxiliary power supply to be provided.
Worst case scenario: a relay circuit to take the PDS Accelerator Card offline unless the Portable is plugged in. You've still got the 68000 for use in the field and then the 68030/MMU and various goodies to run off a tap to the AC Adapter/Charging setup, bypassing the MoBo's power budget limitations for all but the AztecMonster CF Storage subsystem.

The thru-holes on the end of the card are slightly shifted to the back, but no big deal, the card is shown ith them almost directly over the Portable's PDS.
Anybody got a spare HDD carrier to sell me at a reasonable price for the project?
