G200X schematics? was Re: USB ports ?

Ballendo,

The "spiffed-up" schematics are internal to the FPGA. They are the
template for generating FPGA code and do not have any physical
reality beyond that. Because I'm paying $$$ for that coding, I keep
the resulting code.

Once it's done, the resulting G200X board schematic will be made
available as before.

The only difference between what exists now (74HC series logic
implementation) and the new one (FPGA implementation) is how the
concept is physically expressed. The concept itself has been openly
described and remains unchanged.

Hope that helps.

Mariss
