Ok, I'm still a little fuzzy on what your setup is... and what problems you
are having... but...

Don't even begin to mess with the Quadra mobo -- you'll destroy your
computer long before you trouble-shoot a problem (unless you're Terry ;).
What I mean with an "active" port is a 10 BaseT/100 BaseT ethernet port that
is active according to Apple's System Profiler (that is, if you are using a
cross-over cable), or a port on a hub/router that is always on (they are
"active" by default).

If all lights are on on the AAUI adapter the hardware side of things is
*probably* Ok.

Ok, first things first -- try a *short* straight-through cable & hook up the
Q700 to hub. Then, power up. Set Ethernet in the AppleTalk control panel.
Restart if you have to. Try to login to a *known* good Mac also hooked up to
the hub. If that works, then you know your home-made cable is bad (important
to verify, even if it works on the printer).
Next, make sure that you are connected to a known good port!!! (very
important), or make sure that you are *not* hooking up to an "uplink" port
(i.e. port where you'd attach a 2nd hub/router/cable modem).

For this to work you have to be hooked up to another Mac, directly, using a
cross-over cable.

Ok, this is going to be pretty obvious but...
To test for dongle problems, try to find another computer which will accept
an AAUI adapter (nearly all pre-PPC Macs with ethernet, most pre-G3 PPCs).
To test for mobo problems (following above test), you'll need another
dongle.
BTW It might be wise to find a 700 to replace your machine, just in case.
I'm not quite there yet (I hate to part with her... the creature has served
me well for 8 years now), but I could possibly let my baby Q700 go... 20 MB
RAM, no HD (stripped 4 GB to put into my B&W G3).
PS Have you tried moving the Quadra back to its original location?
L8r, Eric.
