Depends on the mouse, depends on the computer.
Quadrature mice are easy. At
worst the "dot pitch" of the mouse won't match the
original and the pointer
will be too fast or too slow. Serial mice (not just
PC serial, I mean any
mouse that communicates via some sort of serial
link) would be harder. You'd
have to know what the computer was expecting, and
what it might send -
perhaps there's an "are you there" handshake on
initialisation. You used to get combined PS/2 and Serial mice for
PCs that came with a little
adaptor. The adaptor only worked with the mice they
were intended for,
because the mouse detected the presence of the
adaptor and sent serial mouse
data instead of PS/2 mouse data.
AFAIK any of the common PS/2 mice can be use as
serial, at least. Not sure if there are adapters to
convert the other way though. Or if they'd work. Can't
see why not though.
I do have at least 1 mouse, a Goldstar branded, that
has a switch to go from, IINM (actually this could be
erroneous) bus or serial. Maybe that is correct
though.
It might be possible to make a "smart
enough" mouse
adaptor that would suss
out what it was plugged into from handshaking
signals, and interface an
ordinary mouse to it.
I haven't a clue what you're talking about mate.
