FWIW, 8.1 is recommended for even 68040-based machines (and not just by
Apple, but by one of those help columnists in one of the Mac pubs).
Stability between 7.6.1 and 8.1 is a toss-up -- they're both rock solid. On
my Quadra 660, I recently upgraded to 8.1 and it seems to tolerate some
older extensions better, so I'd give it just a slight edge in the stability
department. There may be a slight edge in speed, but it's small enough that
it may be psychological. Boot time is a bit slower because there's more
Apple supplied extensions to go thru. The BIGGEST thing is running much
more modern versions of Open Transport and AppleTalk. That has eliminated
any lingering networking hangs I've had. A PPC should benefit even more
from 8.1 because of the larger fraction of OS code that's PPC native.
The things to remember are: install for that CPU ONLY (a lot of the folks
that report slowdowns are installing for ALL CPUs and getting lots of extra
crap they don't need. besides, your system folder will be smaller); try to
do a clean install and use it to take the opportunity to clean the stables
of all the s**t). I can't say much about 8.6 since I haven't moved up to
that yet.
BTW, a fellow at work moved a 6100 all the way up to OS 9 and found it to
work just wonderfully, far better, in his opinion, than 8.1 .
