You are correct about the 5v output.
Ever wonder what the extra pin is on the PowerMac (and Quadra AV) machines
with GeoPorts is?
Yup, you guessed it, a 5v output! :)
GeoPort refers to the capabilities of teh port in addition to its pinout.
GeoPorts on desktop macs are capable of 2Mbps and do DMA. The Newton
