oh yes-- I'm very aware of the yellow you get from tobacco smoke and this
was not that. There was no residue inside the units or any associated
sticky or tar evidence either.
You could also tell where there was more yellowing due to orientation of
the units-- as if they were facing a window or flourescent lights, etc.

I recently restored several VT100 that were extremely yellowed as well
as filthy dirty.
I put the plastics in my bathtub and sprayed them heavily with "Krud
Kutter", intending only to remove the dirt. To my surprise, much of
the yellowing came off too.
Sometimes yellow is color change of the plastic, and sometimes it's just crud. Our
current home was rather yellow inside when we moved in. After I sprayed everything with
windex and wiped it all down, it was back to white. The yellow was simply a large amount
of tobacco residue from the chain smoking late owner.
