[time-nuts] FE-5680A Schematics and scans

Thanks to Ignacio (EB4APL) and the generosity of Mike Harrison, today I received a PCB of a disassembled FE5680A. I provided to make some scans of the board at 2400DPI resolution: the picture size is about 7700x11500 pixel (9MB) Top face (with and without ICs):
