For yucks, I did a google groups search for the earliest news posting
I made from apple. My sig had:
UUCP: {mtxinu,sun,nsc,voder}!apple!aek
ARPA: aek(a)apple.apple.com
This was mid-1988, so that was our uucp connectivity at the time.
I also noticed that my previous posting about MacTCP and Gopher would
have been incorrect, since Gopher servers didn't appear til '91 or so.
