Actually never mind -- I found the capacitor's sister (and it was 16uF,
25V) and replaced it. Power supply is happy again (though it still smells
like fried capacitor).
Unfortunately (previously unknown to me) this system has a very large
battery in it and you can guess what comes next: it's mounted to the
underside of the motherboard and did a very significant amount of damage to
it and some of the system chassis. I can't foresee it being worth the
extreme effort it'd take to repair.
So, two questions:
1) Anyone have a spare Portable II motherboard?
2) Alternately: Anyone need any Portable II parts? Everything else seems
to be working (hard drive needs a bit of coaxing to get spinning).

anyone have a schematic or know what the capacitor at C19 is supposed to
be?
