Telstra already recognise this as a widespread problem. They offer the Apple support # 133622, extension Tier 2 Australia. This offered some hope, but when I rang, I was given a rundown on working hours and told they were "closed". Looks like a long weekend wait ahead.

Background: After installing the MacOS 10.4.2 Update, I couldn't connect by ISDN. I tried the MacOS 10.4.2 Combo, but the result was the same for my G4/800.
