Has anyone considered attaching a three button mouse to a Mac? Before
you decide this is utter lunacy ...

I'm considering getting a (non-consortium) Mac. This means that I won't
have access to cheap beta releases of MacTerm and other goodies. One of
my main intended uses is as a home terminal for emacs; I would like
very much to be able to use the mouse to move the cursor around. Since
MacTerm probably isn't going to provide anything like this (other than
phoney arrow key support, which won't cut it), I figure I'll have to
use SuMACc to write my own (I have other ideas for it too, but they're
not important here).

I also have this "spare" three button Hawley (i.e. mechanical) mouse.
And other random micro hardware. It occurs to me that if the output
from the standard MacMouse is like the Hawley mouse, but with only one
button, I could put a z80 or such between the 3button mouse and the
mac, passing all the motion lines directly, and ORing the button
presses together. Thus the Mac software would work fine. 

But I could get crafty and insert special button press sequences into
the output stream to the host, and Emacs and other programs could take
advantage of three buttons for bindings! 

Does anyone know? Are the squeaks from the MacMouse the "normal" 4
lines of shaft encoder output? Or are they more clever?

Cheers,
chris
