Phew, well spotted. I have re-run the STFM1048 tests and I get the 99% so all good. Thank you.

Re: kodak80 progress

OK, status update for me: Video output seems a bit dark on my NEC LCD with both boards. My video adapter I created does not have any resistors in it at the moment. Currently do not have my video cable connected for audio so no sound at the moment. 1st board All modifications completed (except video ...
