Wow.....finished !
I tested ALL the boards (except the RCR boards, which are simply resistors and caps).
Well, the mission succeeded. We've got 3 working board-sets ! Plus a good number of working other boards.
Some of the defective boards will be relatively easy to fix (RAM replacement). Others, maybe not so easy.
Anyway, the goal is reached. Now, we need to get the board-sets to Denmark and Germany
