extra connector on AGP card with ADC output
i have a sawtooth, which i know didn't come with an ADC monitor. however, i'd like to have an adc-capable card in my parts bin. i looked at one on ebay but there is an extra tab with a few contact on it, maybe 1/2 to 1 inch in front of the agp contacts. i thought apple used contacts 3 and 11 especially for the ADC monitor, but obviously these extra contacts must have some purpose. what are they for, and i assume that G4 machines that came with ADC monitors have an extra socket in front of the agp socket into which this tab inserts. finally, was this design only for the G4, or would this card work in an AGP G5? thanks! this ebay listing has a decent picture of the connector i'm curious about: http://cgi.ebay.com/APPLE-G4-NVIDIA-AGP-ADC-VIDEO-CARD-630-3963-POWERMAC-G4-/250773870717?pt=PCC_Video_TV_Cardshash=item3a6349987d -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: extra connector on AGP card with ADC output
My G5 1.8 single (late 2004) has an Nvidia 5200 card w/ that same connector. My best guess is that since AGP does not have pins for Power and USB, that's what it's for. Only macs that originally shipped with ADC connectors would have that port - so not all G5's have it from what I understand. USB requires 4 pins so 311 aren't enough. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Re: extra connector on AGP card with ADC output
Those extra contacts on the second tab are what carry the +25V DC that powers an ADC monitor. Pins 3 and 11 DO carry the USB signal. To the poster that said USB requires 4 pins - Remember that two of the USB pins carry +5V DC, which is available in the native AGP spec. Only two USB pins actually carry data, hence 3 and 11. G4 machines that are capable of running ADC monitors do have an extra socket in front of the AGP slot for that second tab on the card.

Re: extra connector on AGP card with ADC output
thanks for the answer. followup question, then: is it a reasonable assumption that the vga output of such a card (or the dvi, if a card has that as the second output along with an ADC output) will function if there is no 25V socket in line with the agp socket? thanks!!
