This is all ancient history which I can't remember.
You might even find that QEMUs that old don't compile
any more, depending on how new your userspace is.
You can get older QEMUs either by source tarball from
the QEMU project website or by checking out the appropriate
git tag.

You're trying to do something which is basically
"travel back in time and use decade old hardware and
decade old software to do something that is going to
perform terribly and is no longer supported because
it's just not worth it". There are not really going to
be any tutorials or help for this -- if you want to
do it you get to find out all the places where stuff
doesn't quite work the way it used to and you need to
fix or adjust them.
