That'd be IIci PDS -> generic (?) '030 pinout adapter/PGA Socket -> PGA Male PBX Adapter Card/PGA Socket -> PGA Male Adapter for . . . whatever might work! :approve:
Ditto for the IIfx's non-standard '030 PDS.
That's an interesting notion about the Crescendo NuBus, that's new-n-novel, in the case of hacking support for the HPV Card!
That's one of my lines of inquiry, testing will be simple, just make it work for a 1400 603e ProcCard and the CrescendoPB will work.
A 166MHz PPC 603e/SRAM Cache (?) is a lot easier to come by than a CrescendoPB and an excellent kick in the pants for any '030 PDS Mac in its own right! [

Lo these many years ago, I proved to Dr. Bob, that the 1400 and 2300 are, for all impractical purposes, the same computer. More accurately, he was shouted down by the rest of the 'fritter crew when I posted the two block diagrams side by side and color coded for matches, differences and missing blocks.
The 1400 and 2300 were developed and released in tandem, along with the first PCI architecture PB, the 3400. A few modules were swapped around, upgraded for the 1400's 800 x 600 LCD and the IRDA port hardware was tacked onto the T-REX Daughtercard, which was slated to be tacked onto the Duo's Docking Connector and housed in the base of the UltraDock.
The Duo's '030 PDS Docking Adapter was (assumedly) necked down to 16 Bit for the T-REX PCMCIA Card Cage, though if the IRDA circuitry is on the other 16 Bits, this NuBus Chipset graft will be a piece of cake! A minimum of half of the '030 PDS portion of the Duo's Docking Connector exists on the T-REX Daughtercard's Header interconnect, the other half probably leads to the Video/EtherNet Daughtercard Slot, if not the whole thing. I never looked into that or noodled out the entire T-REX Card Cage PCB, but I've got most of the layers documented in an Illustrator file along with template pics of the progressively ground down PCB layers.
Lovely imagery, very fitting, I like it! [

These just slipped out into .TXT here because PBX suddenly wound up overlaid on the Mac II series 68030 PDS as I was daydreaming about my IIsi/NuBus+PDS Cards Hack . . . with the 1400 PBX/NuBus Chipset sketch in front of me at work.
Two brainstorm fronts collided!
