Hey Clark,
What a coincidence... I'm a bicyclist on the
information super highway.
They are 5v 33uF electrolytics...possibility
polarized? Not too sure (my electrical knowledge died
from malnutrition).
Going to sign off for a few minutes. We live a quarter
mile from the FEC mainline, and a long train being
pulled by three ex-UP SD45's rumbled by, and it felt
as if we were having an earthquake here; to the point
where some stuff fell off the shelves. Weird...

33uF caps are electrolytics. I would suspect they are higher than 5V, more like 6V. The applied voltage is probably 5V so a minimum 6V cap would be used.

They are polarized. Electrolytics are inherently polarized although they can be built non-polarized. Those are rare and wouldn't be in a PowerBook. They shouldn't be hard to find. Even Rat Shack (cough, cough) should carry them. You can go higher voltage no problem. You don't want to use a lower capacitance rating and I wouldn't recommend a higher rating either. In many cases a higher rated parted will work but in some it won't.
