Reverse Engineering of this board has started:
Trace side layout A10_PCB.dwf - the idea is to
locate all the big parts then draw in the traces for both sides of the
board.
Then a circuit diagram can be made for this board. I am interested
in how all the clock signals are generated.
All these boards are double sided, not multi layers like the more modern
boards.
