It's not a standard part, but according to
Samsung's site, it's a 10ns PC100, 3.3v, 144pin SODIMM. I THINK it's only 64MB, although I'm having trouble figuring out that part of the product number.
If you look at LowEndMac, it seems like that is from a Pismo (Firewire G3) Powerbook, though it might be from in a Lombard (bronze keyboard) Powerbook, too.
Anyway, it should definitely work in a Pismo, probably a Lombard. Hope that helps you out.
