Interesting board. Did you use all GNU/GPL software for schematic
capture and board layout also?
BTW, Your LEDs are reversed biased on the schematic. Curious as to
why you put a diode inbetween 5V and the CF VCC like we did on the
TS-7200?
I definitely look forward to seeing this hardware proven and any
subsequent software/hardware cores created. Those will be GPL too
right? We may manufacture this ourself (or quote it for custom
designs) if the BOM and manufacturing costs aren't too high.
We hadn't seen that DVI chip before. We may actually have a use for
that chip out here in the future.
