  Man, that would be a simple fix for me.  I have taken plugin cards
broken in half and put them back together, traces and all.  The Epson
APL card didn't use fiberglass PCB and was very brittle.

  I use a small tipped soldering iron, and a stereo zoom microscope.
I scrape away the green layer off the traces, and use wire wrap wire
and solder to bridge across the cracks.  Can be very delicate work
when the traces are super small and close together.  But that keyboard
is wide open.
