I'd guess it's from a macintosh, an extra power connector.

and this seems to confirm that guess https://goughlui.com/2013/08/18/salvage-stuff … ntosh-g4-tower/

So it would seem that this card is useless in any other machine than an apple, got it.

Thanks!

Yes, that was from a Mac using 24V supply via motherboard's to juice the monitor via the video connector instead of second power cord.

Cheers,

I guess with that being said, is there anything I could do to get this running on a windows machine? I am pretty handy with electronics and don't have much to lose in regards to this card, I don't think it is really worth anything.

It might be possible to crossflash it with a PC-compatible VBIOS from a similar card. That's not something that's usually done, though, usually the reverse, because the Mac cards tend to be rarer and more expensive. Unfortunately I'm not really familiar with the process.

EDIT: In regards to the extra tab specifically, from what I recall it's solely to provide power to the ADC port on the back of the card, and this card would work without power to that port with any Power Mac with an AGP slot. Don't quote me on that, though, it's been a while since I've played with those towers.

As above, ADC power. ADC being a combination DVI-D, USB and power. You can convert back to DVI with adapters or even make your own.

It should in theory work with a PC BIOS, but it’s hardly as if PC Rage 128s are rare or expensive. I’d just leave it alone and get another card.

I’ve got a selection of G4 AGP cards that I’ve gathered to try in my G4 Cube, the Rage 128 being the lowest end card that was offered I believe.

Thanks for the info! From what I am hearing I will just put it in my stash.
