 If the LINK LED stays off, I'd be inclned to
believe the interface isn't
working; on all the devices I've seen it, the LINK LED is on if the network
is live.  Seems odd if the DATA LED blinks when there's traffic, though.  I
wonder what that LINK LED really is for? 
According to the Ethernet Hardware Manual (we finally got a copy from
somebody who also still uses such stuff...YEAH!), the LINK LED will only illuminate
if there is an active connection via the 10baseT network interface, NOT when
using the AUI port. BTW, this is the same way my PC's network interface uses
it.

Yesterday, I went and borrowed a cross-over TP cable from the teacher who
does all the network stuff at our school. Connected it between my PC and the
printer, let 'em power up...and pinging and telnetting both worked!

I verified (by connecting the PC to the Transceiver the printer used WITH
the drop cable the printer used, then telnetting to one of the SUNs) that
transceiver and drop cable are okay. So I think the fault is on the AUI port of
the printer's network card. But no signs of overheating etc. on the PCB...

OK, so far for now...
