  Well, I managed to get the glass back on OK, and used the glue marks to
  line it up. Fortunately the glue stuck back on fairly well when I pressed
  it. I'd write a HOWTO for dismantling the scanner if I thought it might be
  any use. ;-)

  Hopefully, though the GL640 docs show that the chip has at least 3 FIFOs,
  a microprocessor, and a partridge in a pear tree (as a friend of mine put
  it). Perhaps I should post to linux-usb-devel in case someone there knows
  more about the chip.

  I've yet to develop the photographs, but I've made a nice ASCII art
  diagram of the PCB with all the ICs labelled, plus some text printed on
  the board. You can view this at:

  Right, now I'll have a look at the FB630P code!
