One of the LEDs indicates that the main motor has reached its
operating speed, the other LED indicates that the scanner motor has
reached its operating speed.

Now this is weird, I have no explanation for it. It's supposed to
continuously print pages of vertical lines for as long as the switch
is down. Perhaps one of the damaged PCB traces went to this switch?

I would certainly be willing to do it, if nothing else for the sake
of the experiment, since while logic is telling me that the IIISi and
4Si are the same printer except for those boards, I've never actually
tried a swap. The problem is that I would only be able to do it after
I get Peter's 4SiMX in my hands (that's assuming Peter wants to give
it away for free and no one else takes it first), and I don't know
when I'll be in the Bay Area. While having a source of spares for mine
would certainly be nice, I won't make a trip to the Bay Area just for
that. I normally go there twice a year for the Bay Area UFO Expo and
for Conspiracy Con, but the Bay Area UFO Expo just passed two weeks ago
and Conspiracy Con is in May. I don't think Peter would hold the printer
for me for that long.
