Yes, this is first version.Dave wrote:Tetroid, what would happen if you to make the backplane and buffer card a single PCB? The elimination of 2 DIN connectors would cut costs, and signal quality would be improved. It would also be more mechanically stable.
I made 2 boards because of i didnt know, how it can works - good or not good, I checked only repeater board and only backplane board and both. And I can use repeater board for testing any one interfaces outside QL.
For vertical version one board - very good idea, for horisontal version - anyway need additional perpendicular board.
