Does anyone have a list of known bugs in the 68881 floating-point chip?
I've run into what seems to be such a bug (conversion to packed decimal
format sets OPERR exception for any positive "k"), and I'd like to know
whether I'm looking at a flaky chip, or whether this is reproducible
behavior.

I've heard rumors that there are several known bugs in the '881,
and it would be nice to know about all of them...

				thanks in advance
