Yellowing: the Plastic Equivalent of a Sunburn

Printers seemed to be really bad about yellowing. In the day, I sold a lot of
Lexmark, Epson and Okidata dot matrix printers and the old HP LaserJets as well.
Yellowing was a big deal for resale value into corporate America. We used to have
to take the covers off and paint them in order for them to be "acceptable" to
our customers.

The plastics on the old IBM terminals became very brittle and we often had to
use screws to reconnect the rear plastic case back to the front bezels after the
monitors were repaired. We called them "Frankensteins" because of how the screws
looked but it was either that or super gluing them back together after the tabs
broke off. That really made the monitors impossible to repair after that.

I surely don't miss those days. 8)
