Impossible : to tell from each other, And this part is somewhat funny, too, because the PS/2 connector layout is capable of having both devices share the same bus (there's two unconnected pins, which some laptops use to provide alternate CLK/DATA signals). If PS/2 mice used the unconnected pins rather than the same CLK/DATA pins as the keyboard, all machines could simply have two connectors using all six pins and you'd be able to plug either device into either socket. A real "bus" would have been better yet, but we're talking about a spec that came from a company bent on continuing to use simple TTL-based clocked communications with collision detection only available by extra bus lines (read: "bus and tag" 8-). -- -- Todd Vierling <[email protected]> <[email protected]>
