Sure, Macs (that's as good a plural as any) have had networking since
almost the very beginning, and anything since at least the MacPlus can run
MacTCP. Getting ethernet on a MacPlus might be a trick (you perhaps could
use a SCSI ethernet adapter), but you can do IP over localtalk with the
appropriate gateway which I imagine is the way the Mac Classic that started
this thread is hooked into the Internet.
