  Well, I've succeeded in hacking up my Microsoft serial mouse (the
white dove bar one) to work on my Amiga.  It appears to need the following
to get it to talk to the Amiga;

	1> removal of the uP in the Mouse
	2> Add a limiting resistor for the LED's
	3> Change a resistor for the Comparator's voltage divider
	4> A new cord w/9 wires + shield.  (salvagable from Amiga Mouse?)

  If there is interest I'll post the details in a few days.  I need to
find a couple of surface mount resistors to replace the 1/4w tacked on
ones currently hanging off the board.

  This hack is not for the faint at heart.  It requires desoldering IC's
and surface mount parts.  Take apart the mouse and look at the bottom of
board for an idea of whats involved.
