The archive server at which to browse goes by the UUCP name of osu-cis, and
the internet name of cheops.cis.ohio-state.edu.  Look in directory
pub/att7300.

Get either the CAPCTL software or the second fix disk from osu-cis.  CAPCTL
loads in a new keyboard device driver; the second fix disk contains the 3.51m
version of the kernel.  Though strictly speaking the 3.51m kernel is only
guaranteed to work with the 3.51 base software, people have stated here in
the past that it does work with 3.5.

Well, that worked for me; or something similar did.  I don't remember
exactly, but you can pick up "wind.cpio.Z" from osu-cis.  You can set both
the shape and the 'hot point' of the mouse icon with it.

The third disk of the Foundation Set (the "Floppy Boot Disk") is a
filesystem.  To use it, one boots with the second disk, which prompts you to
insert the third disk.  After you do so, the computer gives you a dire
warning about erasing your hard disk.  At this point, hit the break key,
which is at that point shift-escape.  You get a shell prompt, with the
root filesystem being the floppy, and the hard disk mounted on /mnt.

The program "windy", on osu-cis, does this, and probably is able to set
a few more things.
