Yet another small repair question --
Picked up an Osborne 1 with a non-functional keyboard. Upon opening it,
I found that one of the plastic/membrane keyboard ribbon connectors had
cracked partially through near where it plugs into the PCB.
Since these ribbons are actually part of the membrane of the keyboard I
can't just replace the cracked ribbon -- so the only option appears to
be to re-cut the end of the ribbon cable and expose a bit of the
conductive material. What's the recommended means to expose the
conductive stripes at the end? I've tried gently scraping with the tip
of an x-acto knife but it either does nothing or takes everything off
the end :).
Thanks!
