I have a Logitech two ssriva1> button mouse with a round circular plug that connects to the back ssriva1> of the computer. Is this a bus mouse or a PS/2 mouse? dwhite> Well, it's both :-) Those are synonyms. msmith> No, they're not. "bus" mice have a micro hung off the AT bus; msmith> PS/2 mice have keyboard-style interfaces and hang off the msmith> keyboard controller. msmith> Very _very_ different. The above is almost certainly a PS/2 msmith> rodent, as busmice are virtually extinct. Just because bus mice are 'virtually extinct' doesn't mean that he hasn't picked up a bus mouse somewhere. Take it from me, we have hundreds of 'em around here... Although you won't find them on new machines, I will concede. The easiest way to tell is to look at the connector. A PS/2 rat will have a plastic keying pin (an oblong pin) in the center of the connector, while the busmouse will have a plain din-type (I don't think it's exactly a DIN connector) plug (or a DB connector if it's _ancient_.) There is a variant of the busmouse called an "InPort" mouse (I think it's MicroSquash only), I don't know what the difference is between those and bus mice. -- --srj MIPS, n.
