PS/2 mice and serial mice are not the same thing, although you often get
mice which will do both.

PS/2 mice rely on a protocol which is similar to the PC keyboard protocol,
and uses TTL levels. Uses a mini-din connector.

Serial mice use a different protocol (usually Microsoft or PC-Mouse),
and use RS-232 levels. Uses a 9 pin D connector.

Combi/Combo (Combu?) mice usually have PS/2 connectors, and use some of the
unused PS/2 pins in order to implement the serial mouse functionality, when
used with a little 9 pin -> PS/2 adaptor.

I'm doing some interfacing work at the moment, and I suppose this is related!

If there is a genuine interest/need for this, then howabout a PS/2 to Arc
convertor box, and similarly a serial to Arc convertor. Plug the PC mouse
in one side, and plug the other side into the Arc mouse socket. Retail
for around UKP25 inc?

Let's say that if I get more than 10 people who are genuinely interested
in this, then I'll start production - the PS/2 version is likely to
be first, followed by the serial version.

Any interest or comments about the above, mail me.
