    I'm trying to figure out what this slot is on the iMac G3, it's held in by screws. What went there?

    I believe that is the cover for the Mezzanine slot. It was dropped in later G3s.

    There were two revisions of the 266. One had it, one didn't.

    So I was right? It was the Mezzanine cover for the slot. The physical Mezzanine port is on the Logic Board.

    Correct - that is a cover that was used for Mezzanine slot cards. There were no "official" cards for this slot - Apple never published the pinout, and never sanctioned any Apple-made or third-party cards.

    However, there *ARE* cards that use it. My iMac G3 has a SCSI card, which uses the VHDCI SCSI connector. There was a Voodoo 2 video card, that necessitated the use of an external monitor for 3D-accelerated video, it's video port was there. Sonnet also made a CPU upgrade that put a FireWire port there.
