    ...However, note a couple Mac/Quadra limitations:

    (1) The Quadra onboard ethernet interface requires an adapter
    (probably a transeiver) from Apple which costs at least half as much
    as an ethernet card, and we had to wait several weeks to get them
    (thru our campus microcomputer center, but no retail outlets in the
    area had them either; the shortage may be fixed by now).  (I don't
    understand why Apple included only half an ethernet interface ---
    marketing?)

Doesn't it even have the BNC connector that would allow you to
connect it to a thin-wire Ethernet?
