Research really carefully before you buy. Youtube has lots of info. This is old to the point of ancient.. for ancient computer it is great but not nearly good enough for current computers where USB webcam is first second and last choice. The webcam came with 1.0.2 firmware which has no sound on later OS.. and upgrading to 1.0.3 which must be done using Rosetta took me 2 days all up taking a computer back to snow leopard then getting it back to High Sierra.
It was amazing in 2004.. not so much in 2020.
