So I was given a binder of 6502s and a bunch of EEPROMS as a kid. I’m pretty sure they are still sitting in that black foam in a barn. So how does the foam rot

So I was given a binder of 6502s and a bunch of EEPROMS as a kid. I’m pretty sure they are still sitting in that black foam in a barn. So how does the foam rot the pins?

Collects moisture and keeps it right there by the pin. There might well be some chemical breakdown too, the older foam loses its spring so must be changing composition as it ages.

  Ok, so having chips in foam indoors is safe? I have a SID in foam, don't know how else I would store it?

    The more modern foam isn't quite as bad, but keep an eye on it. Clean the pins and replace the foam every now and again.
