Herb's right, but Nick, if I remember correctly you said the computer's in
good cosmetic condition -- which means we'll put it directly into our
preview room instead of into storage.

My modest experience with analog computers is that they have a lot of
electrical contacts, which makes them a candidate for corrosion. I recommend
that this computer be "bagged" while in storage. There are transparent
garbage/leaf bags which can do this job without hiding the contents. There
is no insult in using such bags, any more than there is in putting computers
in boxes marked "laundry detergent" or whatever. I use such bags myself for
my storage of computers.
If anyone is particularly motivated, you can add a sock with dessicant to
the bag. The sock allows moisture to pass. I suggest you buy a form of cat
litter which uses small translucent pellets to asorb moisture; in fact that
material is like "silica jel" and is otherwise used for that very purpose.
Not clay, wheat, pine or woodchips; not clumping litter.
The above is not a joke. Perservation is a serious business, and humidity is
a constant problem in New Jersey. If this produces a string of cat litter
comments I won't post such advice again.
