Quoting Richard Erlacher <edick(a)idcomm.com>om>:
The "gray" rather than black color suggests
that it was left
outdoors for at least a season, or in the window for a year or two.
It's probably sunlight. It sat on the floor in a remote corner of
a high school science lab for possibly as much as 10 years. It was
close to a large bank of windows and got lots of sunlight. The grey
is very *very* dark, and I could have mistaken it for black easily.
What all's inside this critter?
Power supply, keyboard, motherboard, Disk II card, and a printer
card.
