It seems
strange for the drive to look so otherwise perfect and
these items to be mush. Any thoughts?
Storage conditions, especially atmospheric ozone. I spent 6 years
living in LA, and the lifetime of my natural-rubber bike tires there
was measured in months. Foam would either dry up and turn brittle
or go the other way and turn gooey, typically within a couple of
years of manufacture.
Obviously temperature and exposure to UV light/direct sunlight are
factors too.

Well, heat I'd buy, but other areas of the drive would have shown
the effects of sun, and the hub is inside, away from light.
I was wondering what storing the unit in the presence of unsealed
containers of petrochemicals might do... or even worse, whatever
a medical school (formaldehyde?) might have in storage...

Hi
The biggest factor for rubber and plastic, other than
UV light, is oxone. Even a little will change rubber to a
gummy mess ( chlorine gas does as well but that usually
isn't an issue ).

New subject: Apple III Motherboard
A while back, someone was looking for an Apple III motherboard. I talked
with a guy a couple of days ago who said he had one for sale. If whoever the
person was is still looking, let me know by email and I'll send this guys
email address. Thanks.
