John,

Ah. At least you can then sketch them as you unplug.

Indeed. I found the front panel header (the most important one because of
the multiple connectors being plugged onto it ) due to the non-standard
usage and the omnious scribblings under them. 20-pins with pin 11 broken
out. Alas, those scribblings do not make it clear which pins are actually
used. As such I've only been to identify the connected ones (the power and
HD leds and ofcourse the power switch), but no such luck for the "reset"
"G-led"(?) and "speaker" markings.

I've already tried to match them up with some standard configurations, but
have not been able to find a match.

Most of the other headers are boxed with slotting and all of different size,
so not that easy to mix them up. The only one I have to jot down are the to
dual USB headers. Althoug later versions can be inserted in either
orientation, these ones do not look like them (10 pin, last two pins not
used).

That leaves a few small 4, 3 and 2 pin slotted headers that currently are
not used. Could make some guesses about them related to their forms &
location, but thats perhaps for a later time.

(Remember - if there are no omitted pins or other such indication - to
note the orientation of the connector[s]!)

:-) I noted down the color of the wires going to each pin.

Only things that won't be obvious is the orientation of the LEDs, which
you can _probably_ determine with a multimeter (most multimeters will
light an LED

Yup, especially when the multimeter has a "diode" position in its ohms
range. Though normally I just plugged the "new" leds in and checked if
they would light up. If not I reversed their polarity. Hasn't failed me
yet. :-)

Thanks for the suggestions.
