[Coco] This CoCo has a TAN!

[John Guin]

That color reminds of the exact same color the white paint in the crews
lounge on the USS Ohio had turned after being exposed to cigarette smoke for
20 odd years.

When we were tasked to repaint the lounge while in the yards, we could not
tell what color it had been and thought "mushroom" was the original color.
It was only after that paint obviously did not match that we scrubbed down
to the original white.

I wonder if that machine had been sitting in smoke for all these years -
most of that might wipe off with some 409 and elbow grease.

Yes, it's supposedly the fire retardant chemical that causes the
discoloration on so many different light colored classic systems. Lots of
people swear by retr0bright and do it on a regular basis, but I've been
concerned about reports that the effects have started to wear off in as
little as a year. If it was a permanent fix, I wouldn't have an issue with
it, but my concern is that additional applications will further weaken/make
brittle the plastic. In my collection I already have a few non-treated
systems that have brittle plastic from age (e.g., an Exidy Sorcerer,
Videopac G7400, and even a Sony CRT TV). As a collector who also likes to
use all of his stuff, I'd rather put up with the discoloration than risk
compromising the case's integrity.

In any case, I guess we'll know better the long terms effects of retr0bright
and similar processes in the next five years or so.
