i have been working on a DJGGP mouse routine as part of my TRW (the reinvented
wheel) project.  to get what i have done for the mouse so far, goto:

(i just uploaded it for this message and do not prommis, or even think that i
will keep unloading more copies).  It is still under improvement, so chill if
it aint all that you want...  -- it doesn't even have locking or mouse
clean-up!!!

as far as i know x and y are never packed into one register.  x is usually in
cx and y in dx.
