I've experienced the exact same problem with two HP-71B soft cases: lots of fine, black dust, that was very difficult
to remove from the LCD display, keys, ports, etc.
It seems to me that after 15-20 years they disintegrate
spontaneously, as the cases are brand new on the outside.
I've tried to remove all the dust but to no avail. The
"solution" is to keep the 71B themselves inside a thin, sealed plastic bag, then that plastic bag into the case. This
means everytime I use them I must use a new plastic bag,
but at least it keeps the potentially dangerous black
powder at bay, while protecting the machines inside their
As for finding replacement cases, it isn't hard, only
expensive, and probably pointless since the replacements,
if original, are likely to disintegrate as well.
