Whoa! If all those pins are really bridged and that's just not glare, yeah,
that would be a problem. Luckily (sorta) the Newton is smart enough to not
use that chip as I would expect it is not passing basic tests on bootup.
I don't see how anyone could have gotten that all covered in solder... is it
loose debris? Maybe you could take a thin X-Acto knife and *carefully* cut
between the pins - trying not to dig into the PCB underneath. YMMV, Standard
Disclaimer applies, etc.
