The new boards arrived, assembled one, and found there was a track error!, at least this one was minor, so a bit of cut/reroute solved it, and it now works as intended.

It has new features, like jumpers for "quick" calibration (you still need a tester to properly position the (calibration) pots, or you will have a very odd looking screen mapping, wich will NOT be square).

There is a video (vertical, sorry), with the working hardware here:
