yep.... that's what i did. four hours later i had destroyed the connector
because the graphite had come off. what partial information that did have
was of no use.
destroying a keyboard and examining the flexible PCB was what did it:
i found that the layout was ROW1 ROW2 COL1 ROW3 COL2 ROW4
ROW5 COL3
nothing that was even remotely sensible!
