Logitech Quickcam Connect Driver For Mac

My parents have an old Logiteck QuickCam, like I use, but the video doesn't always work and then when it does sometimes the picture is very dark.
I bought them a Logitech QuickCam Communicate STX. My folks have a Mac Mini running 10.3.9.
I knew I would have to find a work around. I vaguely remembered doing that when we first set ours up almost 4 years ago. I just checked on my 10.3.9 and cannot find Macam or iUSB Cam on my computer so am not sure if I will need it for them.
I think I downloaded Macam for them. What should I see as the download from macam?
I also downloaded the iUSB Cam.
The camera did not work.
Found this site, but want to know if you think this will do it?

I am not at my parents' house now, but will be later this week. As my father is quite ill it would give me great comfort to be able to iChat with them when I am not there.
Thanks for any help you can offer.
