That might be bromine, which was used as a flame retardant back in the days (and probably still is, but I'm not sure).
A lot of retro gamers are dealing with this issue, giving their beloved Game Boys, C64s or whatever a yellowish look.
Some folks got together and created a mixture they call "Retr0bright" [1], which consists of hydroperoxide, Tetraacetylethylenediamine (TAED) as a catalyst, and finally uv light. It "reverses" the effect, though it might reappear after time.

- Theodores 7y agoActually it is an evolving game. It is just the UV that restores the whiteness back in most cases. Restoring molecules is not necessarily it, the TAED catalyst sounded plausible, but a lot of retrobrighting goes on with just the peroxide solution and sun. But even then the peroxide was found to not be it. Indoors you don't get the same UVA/UVB as outdoors, so it initially seems counter intuitive to think that that yellowed computer case would go white again if put out in the sun. But it works. No voodoo chemicals needed. It comes down to bones and how they always end up white, bleached from the sun. Try it.
