I have resurrected my old g4 ibook with OS X 10.3.9 - the Safari on it is so out of date, and the cpu is so slow that surfing is impossible. But I use it for command line stuff, and Textedit to keep my journal on. But I wanted to remotely logon onto my new Macmini. I couldn't find a backup of my old Chicken of the VNC I used to have on it. I was pleasantly surprised that the dmg download of this s/w still works on the old OS - so I am in business again. Thanks administrators!
