I am making an effort to stop being a Luddite and get used to the new technology but it is fraught with problems.

Every time I try to start Classic I get a bus error which tells me to start again with extensions off. It does not work with the shift key but will start up with extensions off from the Classic panel.

In desperation I swapped back to System OS 9.2.1 and used it without problem yesterday but today when I swapped back to OS X.1.2, Classic still crashes.

In order to use OS X I installed Eudora 5.1.1 for OS X and Mozilla X 1.1a. I also installed the Software Updater update (before I did the updates it wanted to do so it seems I have made another mistake). I presume these would not have changed the OS 9 System Folder. It appeared to work OK on Sunday after I had done all of this. I had Classic set to start up automatically because I use it so much, I have turned this off but it makes no difference.

I am fed up as I am achieving nothing and spending all my time trying to make the rotten machine work! The help file is not too helpful. Any suggestions please?
