a charm ;)

I started updating my blog with (hopefully useful) information.
I did a write up on the SGI Indigo so far and will update it with future
findings. It's at http://ethan.757.org/?p=32
I made a list of all the tantulum SMD capacitors of the style of the one
that fried. I think I figured out digikey part numbers for most (And
published the sizes I measured of the caps.)
If the cap that fried belongs to the audio section, I was thinking maybe
those components use negative PSU voltages (op-amps, DACs) so maybe the PSU
is doing something funky. Finding a pinout for the Indigo PSU might take a
little bit of work -- but since I have mine apart I should be able to
document some of it.
So many projects!
