If you haven't got the dro board to work yet take a real close look at the
solder side of the board, where the LS7261 chips are. there are a couple
of traces that are very very close together. It's easy to get a solder
bridge there.

Also you can try a program I wrote in VB to read the dro board it's located
at http://www.star-telegram.com/homes/scalione/VB_Dro.zip

It's not perfect, and you can be the first to try it.
