One thing to note about almost all the mirrors (Including the internet archive's one) is that they are missing the Mac OS 9 Updates, as you had to go through a additional SLA page. Unfortunately these seem to be broken on apples server as well.
I Did find a few of the updates and they are available from my copy, but most of the language specific ones are missing
What directories would these be in? I have:
