I recently acquired an HP 87 that I was able to repair, all except for a
few sticking keys. From digging through the archives at this site and
the HP-80 Series sites it seems the only way people have found to fix
these is to cannibalize the plungers from other similar keyboards. Has
anyone figured out a way to repair these cracked key plungers yet? I
have tried a few things like gluing and wrapping and melting, etc, with
little success. Does anyone know a source for these plungers? The HP
part number 1535-4043 still comes up on HP parts site with no stock.
