I want to connect a Quadra 700 and a IIci with an AppleTalk network so
that I can use filesharing to transfer ~100 megs of stuff between
them.

On both machines I'm running System 7.0.1, Network Control Panel 3.0,
AppleShare init 7.0, AppleTalk v58.0, and Sharing Setup 7.0.

For the LocalTalk connection I've tried both PowerUser LocalTalk
connectors from MacConnection and PhoneNet-type connectors (obviously
I didn't try to combine the two types of connectors).  I've plugged 
the connetors into the Printer ports on both computers (I've also
tried the Modem port, but that shouldn't work, right?).

I've turned on filesharing on both computers and shared both hard
disks.  Then I open the Chooser and click on the AppleShare icon,
which should display all the fileservers on the network.  Nothing
shows up.

I've read the comp.sys.mac.comm faq and the Mac manual, neither of which go 
into much detail about setting up a LocalTalk network.

I've been able to connect both computers to the campus-wide AppleTalk
network we have here, so I don't think there's anything wrong with the
Printer port.  And apparently I've got all the necessary software
because I can share my computer across the campus net.

What am I doing wrong?  I consider myself an experienced Mac user,
but this AppleTalk thing has me completely baffled.  It seems like it
should be easy to do.

Any help would be greatly appreciated.
