   This does raise an interesting question: would it be possible without
*too* much difficulty (save finding the necessary equipment) to do
multiple x-ray scans of the MP2000 PCB (it's probably 4-6 layers),
clean up the image, then run it through a program that would reproduce
a schematic (after tediously entering in values for the.. oh 60-100-odd
components on the board? Can such precision focus x-ray even be done
(or more to the point, *has* it been applied to reverse-engineering - I
read that such beasts exist), and does such
schematic-generating/rearrangement software exist?

   Or have I not had enough sleep lately?
