I was hunting for odd bits in my piles the other

shocked at the decay of several plastic parts. The ends of a
set of GPIB cables for an old CBM disk drive were covered in a
white powder coating - not mold, but slow decay of the plastic.
I have been seeing the same thing with my C= GPIB cables (as well as
certain tool handles from the same era). AFAIK, it's inevitable with
that sort of plastic.
My RK05F has a white powdery junk all over the inside, and all the plastic
bits have hardened (some have shattered). Is this the same problem? I
figured something had caused all the plasticizer to boil out or something.

PC-7 is a good replacement for damaged plastics available in most hardware
stores. It is an epoxy in putty form, it can be drilled, machined, sanded,
formed, etc.
