Thanks, guys !
For some reason, I skipped the reversal of connectors on the C board in the manual !
I can't wait to get home in the evening and check things out.
I'll check it and let you know if this helped.
Oh, and one more thing:
I've just realized that it's a PIN-CUSHION, i..e: a cushion for pins.
I always thought that it's called a "pinch-cushion", because the pins
"pinch" the cusion :-)
Thanks again !
