testing an 8087

[oblivion]

Are there any special tests or programs to tell if an installed 8087 is actually working. I know there are programs that can tell if one is present. Is that enough? If it's detected does that mean it's legit? I ask because I wonder about a few cheapo ones I ordered from China in the past.

An earlier thread on the subject is [here]. Testing is covered.
