RE: HP 71B cases and the Black Cloud of Death
the foam of my two hp 71b-cases desintegrated as well. when i pressed hard on that black dust with my thumb, it became sticky. now i keep the calculators, which are both in perfect condition, in plastic bags. i did not like the idea of having some kind of tar-like substance on and in the 71s. i threw the cases in the trash.

regards,
hans
