    The iMac is a G3 Slot-load SE, and the PowerMac is a G4 450MHz AGP.
    I happen to have an AGP that only came with the telephone jack, but no modem card connected inside.

    Both modems look the same in photos: 661-2213 (slot load) & 661-2186 (AGP).
    Is the only difference that the newer one has flex K56?

    If anyone has tried this, or would care to speculate please reply.. Thanks

    They may look similar, but Apple used a couple few busses and connection methods for modems.

    USB and I2S being the most popular, but they tended to modify the modems and connectors to fit the available spaces in the PPC days.

    If you can find the exact machines on the developer note site, you may be able to find out which bus each used for the modems.

    I2s

    Thanks for the quick reply. I did find the developer notes published at the time of my production dates. Both describe a Key Largo controller(~) using I2S, however the Pmac also describes special DMA for it's modem. o.k.; prob won't work.

    Incidentally, the later iMacs use an "Intrepid" ASIC -- and now for something completely different.

    Thanks again for the link.
