Will this USB modem work on a G3 iMac?

[Dennis S]

I may just buy a sub-$10 PCI modem off ebay for the PC to get me back online. Do they all pretty much fit a Compac SR1103WM running XP? Are there any specific specs to be aware of? I don't care about the speed other than it being 56k.

Edit:

I just ran across this one that's the same brand as what's in it:

I'll come to the library Tuesday and buy it if I don't hear anyone object.
