My problem so far is that when I go to the Apple Talk setup I cannot get it
to select Ethernet on either of the G3's. It says that I should check my
connections. I have tried the simplest connection of all by using an
Ethernet cable directly from the G3 to the Apple printer. Restarted a couple
of times and I could not get a connection. What am I doing wrong? I figure
it has to be something really basic and simple, but like the good or bad
moon, I am not getting it. Can someone help me?
Usually if you can't select ethernet in OS 9, the computer can't see the hub. So it could be that
a) your computers' ethernet circuits are bad, or
b) your ethernet cables are bad, or
c) your hub isn't working.
Since you are having trouble connecting 2 computers, it seems most likely to me that your hub is the problem. I would try a different hub or, better yet, a switch which has the same function but directs traffic only to the computer that requested it.

A hub is not the same as a router. A router does a lot more, it stores information about all the computers and printers and negotiates between them. A hub just allows you to add computers or network printers to a subnet. Another thing is you might have a crossover CAT5 cable where you need a straight-through CAT5 cable. It matters with some hubs and routers. The proper way to get this to work would be 4 straight-through cables spidering out from a router to each computer and printer. Each one would need an address in the router's routing table, and you need to get into the printer to tell it what its address is. I have a 16/600 attached to my router and I can print from my iBook, my G5, and my Wallstreet. I needed to set up the printer's address with the printer utility, then put that address into the router.
I'm with these two guys: my first guess is that it's a physical-layer (OSI model) issue, and that means your cables or hub is probably bad. Or, as Timothy suggests, you could be using the wrong type of ethernet cable.
To tell what kind of cable you have, you'll have to look at the wires in the connectors at each end. Look at this page (http://www.cabletron.com/support/techtips/tk0231-9.html) for details on how to check the wiring in your cable.
If you are connecting device-to-device (where "device" is computer or printer), you need a crossover cable. If you are connecting device-to-hub (or device-to-switch), you should use a straight cable.
Even if the wiring looks correct, you might want to use a continuity tester to check that the pins are wired correctly.
