Good job -- very clever Y-split technique! Thanks for the detailed photos!Just following up with confirmation that the Raspberry Pi 1 B+ did indeed work just fine thanks to the identical GPIO pins. I was completely out of my element while doing this so I've attached a few photos that will hopefully help others. For the Y-split of the 3V3 pin I was able to get some great results by completely removing the plastic shrouds on two male pins and one female. Additionally, the SOIC8 clip I got didn't have enough spacing for the cables to be plugged in with these plastic shrouds. I ended up sawing off the plastic to expose more of the pins in order to bend them.
The process seemed to go without a hitch as shown in my Thunderbolt Bus screenshot. I unfortunately do not have many devices at the moment to test TB3 since they're at work, but I do have my DeckLink mounted in the Sonnet PCIe Breakaway box. Results here were interesting as the card works if it's powered on and plugged into the AIC Titan Ridge at boot, but hotplug does not work - it gets detected but shows up under PCI as if the drivers haven't been installed.
Thank you so much for all the research @CaseySJ and @Elias64Fr .
With flashed add-in cards we tend to get the best results after hot plugging a Thunderbolt device while macOS is running and then doing one reboot. It won't be perfect, but if the limitations are known, we can try to accommodate those limitations.
