How do I identify my Matrox Graphics Card?

[Jorden]

A question from Ancalagon:
I recently pulled a Mystique out of an old machine. Is there a way to identify which card I have from the markings and tags so I can download the correct drivers and maybe an manual?

Thanks

A couple of answers for him, and probably for you, if you find yourself in the same situation, can be found in this thread in Matrox Hardware
