Hi David,

That certainly is a shame.  For the gold plated contact to corrode so badly
means large amounts of potential damage to the flexible PCB.

You may be able to repair it using some brass shim - but I cant see how
else to repair it.

The CX was a wonderful machine - and seeing this has reminded me of many a
night at uni.

Kindest regards,

Doug Jackson
