Did you miss my post that I got it working after reheating the
connector pins. I can also run Ver66.9 at both 600MHz and 528MHz
with TCXO defined.

Yep
that¡¯s it and its in the right orientation.? The U1 part
should be on the board 180 degrees from straight up and I
think you have that right too¡.. with pin 1 at the white dot
in the lower right corner¡

One
thing I did that I regret is placing the ¡°U1¡± symbol at
the bottom of the IC.? The little white registration dot
for PIN 1 is at the bottom right.

Completed the build for 5V. No shorts, no opens, and all
connections traced and ok. However, with the Board in place,
no Display. Checked it twice and made sure that both
connectors were fully seated. The system still works without
it, so no harm. I'll try again later and check some
voltages.

Got it yesterday, heading out to the workshop to
build it. May have missed your note on 5v/3.3v.

I sent out five of those new
display driver boards about a week ago and only saw
posted that Terrance got his working as was able to
use a 3-foot long display cable without display-T41
errors/lockups. Anyone else built it yet? I know i
didnt publish an assembly manual before i headed out
of the country but the thing is pretty simple and i
did send out a note re how to make it work on 5v or
3.3v.
Anyone else? I think its a
winner but would like to know so i can get parts
and boards ordered to send these out before
