Hello Pete,
at first: Is it okay to continue our mailing this way (directly mailing the
messages, only CCing to Classiccmp.org? It's because I'm on the Digest and it
has been arriving at about 4 P.M. local time the last few days, which is too
late for me to stay in school and pick it up the same day (alas, don't have
Internet at home yet).

No, nothing on that board. There are only two 2pin jumpers, one for printing
out the adapter's status page and one for resetting the NOVRAM contents to
the factory defaults. I think I've already seen what you mean on other network
devices (six or so 3-pin jumpers, the movable parts sometimes joined in a
blue plastic tray).
>>But no signs of overheating etc. on the PCB...
OK, I admit that was only for VISIBLE SIGNS. The LM2577-T12 (switching
voltage regulator in TO-220 package) next to the AUI port becomes TERRIBLY hot
even after < 10 minutes of running the printer.
I assume it's used to generate the voltage the Transceiver uses? But the
power light (on the transceiver) is on as long as the printer is...
And even worse...the DATA LED does no longer blink when there's traffic on
the Ethernet...
OK, I hope that helps
