So what style of mouse is it? Of the aforementioned DE-9 mice, the C-64
has a microcontrller in it that does some odd stuff to be backwards
compatible with the machine (so it's not portable), the Amiga (and the
original Mac) use raw quadrature and individual button lines. The PC mouse,
as you mentioned is serial (not "serial"), though the microcontroller in
most later versions knows how to tell it's on an RS-232 port or on a PS/2
mouse port via an adapter - so if that mouse thinks it's on a serial port,
it talks one way, and if it thinks it's on a PS/2 port, its protocol is
different.
So how would you characterize the MSX mouse? Raw? Processed? Serial?
Odd?

That's just
how it goes! OK second part of my question then: what about
the mouse? What other more easily obtainable mouse would work on the MSX
machine? Commodore made mice with 9-pin connectors for the C64 but I
doubt it would work or the Amiga one .... and of course, the "serial"
mouse from a PC I would expect won't work as well.
The MSX Mouse is compatible with very few devices. Some Sony video
equipment (like a picture computer I have) and NEC PC-98 computers. Ah, the
Roland S series of samplers (S-50, S-750) uses the same mouse/trackball.
You can build an adapter with a small microcontroller. The schematic is
around the web, I can send you if you need.
