µPF--2 : Final Beta Version

By reworking the layout of the components, I finally had enough room to implement all of the extension connector signals. All I have to do now is to create the printed circuit board:

The final circuit is quite large in the end, given all the elements that are implemented.

Eventually, I hope to be able to operate these various original expansion boards knowing that they are intended for a µPF1P and not a µPF1 or 1B :

Printer & I/O boards.
