I'm still using a six year old 840av myself, and am in no rush to upgrade.
It still remains to be seen whether older Pmacs will be dead ends soon and
the new stuff is godawful ugly.

Regardless, it's no big a chore to maintain compatibility with older file
systems, especially plain HFS. It makes more sense to use it over HFS+ until
you reach a gig or so.

There is a mapping which 8 uses. It's only in the file sharing software that
you get the reduced privileges. Presumably with real Appleshare it's the same.
I don't use 8.0/8.1 on anything since it got ugly and slow. And I don't have
anything which will run 8.5.

Didn't know you could block edit the tables, just the volumes. Cool if you can.
