Idea about Agp to PCI Adapter
Apple G4 Cube does not have AGP port, only PCI, but there is very interesting Apple 820-1102-A Cube Video Card Riser Board[http://www.kpsurplus.com/buy/apple_820_1102_a_cube_video_card_riser_board/36302]. I think that it can be used for PC. G4 Cube Manual you can download there [http://cubeowner.com/manuals/replacement_parts.pdf]. I have bought one, but when I put into the PCI slot even without any videocard PC does not start, may be it is necessary give additional voltage on J4 or J6 pins or to isolate some pins or something else. If somebody have any ideas about it?

doing a quick google doesn't show a lot of info about this adapter.. but it certainly looks like it requires some extra juice and maybe signaling from the motherboard?  J6 looks like a power connector to me..

I'm also do not find more info? but I think it could be worked, and one of two connectors must be power. If somebody get this device to work it would be the cheapest AGP adapter! It costs only 20-30 usd.

yeah, that would be cool.  Maybe if someone has a G4 cube we could see what those leads do and kind of reverse engineer it.  Maybe start with the manual?

More closer view, any new ideas?

no ideea mate, but the ideea is very cool !
We need to find a Apple owner, who can measure the voltages on the connectors.
