Maybe SPF 50?
Seriously, I'd say probably limiting exposure to sunlight and/or florescent
lighting. I believe some (all?) clear polycarbonate plastics will filter UV as
well to some degree, so maybe a clear case?

Subject: How to prevent yellowing of equipment on display
I know that there has been a tremendous amount of talk about removing yellowing
from vintage equipment, but going forward, does anyone
have any suggestions for
helping prevent yellowing of equipment on display, short
of keeping them in a
dark cave? I have a couple of Apple II's that are in excellent condition with
minimal yellowing and would like to put them on display without having to worry
about damage to the plastic.
