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 Hamvention
