In my searches for newer and bluer mouses (not Big Blue, though), I've
come across some interesting stuff.  
   1) There are now 2 (count 'em, two) trakballs masquerading as mouses for
the Mac, one by Kensington and one by Assimilation.  They both seem to be
decent replacements for the mouse, although I haven't used either for very
long.  The Kensington one (TURBO MOUSE) was $109 at the Cornell Campus Store
(not usually cheap, so the real price is probably lower) and the
Assimilation one (MAC TURBO SOMETHING) was $89. 
   2) I just read an article on the amiga newsgroup about someone having
Amiga mouse-compatible trakballs for a mere $19.95.  I can get the address
easily if anyone (beside me) is interested.
   3) There are a number of optical mouses for the clones, usually around $100,
from what I can tell.  Could these be changed to work on an ST?
   4) A new Atari Mouse is something like $40 - $50, I believe, so an
alternate control form is not a problem economically.

Has anyone heard anything about any of these options for the ST?  And as a
final and repetitive note, would someone please post a list of runs/doesn't
run files for the Sac?  I'll summarize anything anyone wants to e-mail me
peronally and post to the net.  Thanks . . .
