It's common on old boxed Acorn hardware; I've found a few where the mains
cable has steadily oozed its way through the polystyrene packaging.

Interesting, I didn't actually know that - but I got into the habit of putting
the mains cables of aforementioned boxed Acorn stuff into bags as I figured it
would *probably* stop further disintegration (of the packaging; I'm less
worried about the cable as that's easy to replace!)
