. . . hopefully!

Start of this project was info about the anemic TAM PSU issue from many sources, here, Tinkerdifferent, WWW and ThinkClassic back in that day.
Was working on putting together a better Initial Post, but what the heck . . . just chuck it out to the pack of wolves! :p

Looks to me like only 12V & -12V would be handled nicely? Those are for disk drives, no? What else?

Whatcha' think? Is is even possible to take the pressure off the TAM's pathetic 5V and 3.3V rails with an AuxPSU Hack on a new riser design?
Next evolution of the project will be TwinSlot/TAM in the upper right corner. 6360 version PCBs are in, look good and on the way to me for function testing . . . very soon now!


edit: typo in files, the 6" Pigtail is USB-3 running in Mac supported USB-1 role.
UCB Pigtail should bee Tight angle for USB card interface
First notion was a PicoPSU inside years ago, but recently been thinkin' about USB-C.
