I pulled the cards out of both of my Beige G3's and noticed that there is a port that fits an IDE cable just fine. Also, the card with actually A/V ports, not just mic and sound out, has another larger port, that wouldn't be SCSI? Anyone know what these are for?

It may be the same number of pins as IDE, but used for something else. I've seen similar things on old sound cards (for connecting to expansion cards).

From the Developer's Notes:

The DAV Connector

The Audio/Video Input/Output Card has a separate connector called the DAV (digital audio video) connector. The DAV connector provides access to the Audio/Video card's 4:2:2 unscaled YUV video input data bus and associated control signals. By means of a 60-pin cable to the DAV connector, a PCI expansion card can gain access to the digital video bus on the Audio/Video Input/Output Card and use it to transfer real-time video data to the computer. Such a PCI expansion card can contain a hardware video compressor or other video processor.

The DAV connector accepts YUV video and analog sound from the PCI expansion card.

The 60-pin DAV connector is located at the top edge of the Audio/Video Input/Output Card. A PCI expansion card that uses the DAV interface can be connected to the Audio/Video Input/Output Card with a 7-inch 60-conductor flat-ribbon cable.

The Apple DVD-Video and Audio/Video Card does not include the DAV interface.
So that's the 60-pin connector you point at with the red arrow. (SCSI, by the way, would be 50 pins.)

The brown slot on the cards, just above the gold card edge connectors, is the modem card slot.

I believe the black connector with the two tall plastic prongs is the RGB output for the internal monitor of the All-in-One G3's. Obviously, this connector goes unused on regular G3 desktop and tower models.

The last connector -- the smaller white one at the top edge of both cards that you think might be IDE -- I don't know the function of, but I know it's not IDE.

heh heh...it's definitely not IDE. After looking at the pics, i realized the top one has a burn mark. Then I remembered before I posted this i hooked up a hard drive to that slot for fun...the computer turned on, shut off, and I smelled something hot...
It's okay, the card still works and the computer only cost me $2 so I wasn't too worried about killing it. But it's not IDE.
