Probably been at least 9 months since I last booted up my dual-processor G4 PowerMac. Only one issue with it: the Ethernet cable had to be removed from the ISP-supplied router because the connection is dodgy. As I now have an AirPort Extreme, I have spare reliable ethernet ports, so I used one of those. I was able to update the TenFourFox web browser, ClamXav anti-virus & download/install a single-site browser app, TenFourFoxBox.
