Hi Denis,
I do not have a G4 but I can make some suggestions for some of these
things if you have not had any help already:

Great.

If you have MOL in full-screen then it is on another "virtual-console".
You can try pressing things like ctrl-alt-F7 [the usual screen is on #7],
MOL should be on the next free one, #8. Numbers 1-6 are simple text
consoles. If ctrl-alt does not work on YDL try control-F7 and fn then
ctrl etc. Alt is usually the apple key but may be "option" depending on
your setup.

Ahh, but does your kernel think that it is on a G4 ? Altivec support must
be on in the kernel. How do you know MacOS thinks that it is a G3 ? Look
at the loggin messages from startmol and it mentions altivec. This is the
true test of whether altivec code will run in MOL.

None that I know of. The graphics are not hardware accelerated in MOL so
most things are slower. On the flip side you might notice faster file
operations and virtual memory which linux is better at than MacOS.

Yes. Look at the options to startmol. One of them loads the kernel
modules [which is what root-ness is needed for]. Something like startmol
--loadonly. Put this at the end of /etc/rc.local or equivalent. This
will get run as root every boot, then you should be able to do startmol as
a normal user. Unless you try some clever options you will only be able
to boot one MOL at a time though.

I have found the "Location Manager" to be precisely designed for this
scenario. It can have different extension sets, sound settings, TCP/IP
settings etc. Are you sure that you need sheepnet ?
Good Luck,
