On converting Mouse Systems mice:  it depends...

The orginal Mouse Systems mice for the PC did have three buttons
and used only a 200 cpi pad.  There were two versions of the three
button mice.  "Very old" (~1987) units required a small battery
eliminator transformer.  The slightly newer 3B mice were self
powered.  (Incidentally, I suspect this might have had something to
do with devices that are self-powered from the serial port; there
is a patent out on the technique -- I forget who holds it at the
moment.)  The three button mice send a five byte protocol that is
the same as Summagraphics devices (and I think Logitech).

The newer Mouse Systems two button mice are self powered and use a
three byte protocol that is the same as Microsoft mice.  The newer
mice can sense either a 200 or 400 cpi mouse board.  There have
been several different types of mouse boards: metal and plastic.
The best boards were the 400 cpi boards that came with the later
Sun-3 models (my opinion).  The mouse boards are available in
several different sizes.  One used to be able to get mouse boards
from Mouse Systems directly, but last time I talked to them, they
didn't want to sell in less than OEM quantities.  I like the Sun
verision that is about 15 cm * 15 cm.

I haven't had a chance to try out latest Mouse Systems PC mouse.
It looks like it comes with a very high resolution board made of
aluminum.

The only bad thing about MS mice is that I've had several old ones
that blew a CCD line sensor.  I'd have thought the LEDs would go
out, but I haven't had that happen yet.
