I'm having trouble taking clear, well-lighted photographs. If I get
too close, the lens blocks the flash; if I back off, it ends up being
blurry.

Once I get my lighted magnifier, I should be able to take better
pictures through it.

A flatbed scanner works surprisingly well.

Use a white plastic grocery bag over the flash to diffuse the light.
You might want to add a stop to compensate.

The adapter connects to the J1850 (and, in some cars, the GMLAN) bus
in a GM car. It emulates the commands of the factory XM Satellite
Receiver module; as far as the stereo head unit can tell, it's talking
to the XM module. The module connects to (and controls) an iPod audio
jukebox and routes the audio output as well as song information into
the car stereo head unit.

How's this?

I think Henri wins the prize!

Not only do the oscillator pins match, but several other pins also
make perfect sense. If we assume that the 6-pin header is a BDM port,
then the pins on the header and connected to the right pins on the
micro. The CAN TX line leads directly to pin 1 of an 8-pin part which
is probably an MCP2551. The 5 DIP switches in the red package on the
right lead directly to 5 GPIO pins. 

Anyone know where I can find a cheap development kit for the MC9S12C?
Then I can ID the part exactly. :)

Still a mystery, however, is U6. This 14-pin part definitely seems to
have something to do with the J1850 interface (two of them, actually -
one to the XM receiver module, and the other to the stereo head unit).
So far I have had no luck finding any likely candidates for this
sucker.

Anyway, thanks, guys, for all your help! As another poster said, this
stuff is fun! :) :)
