  • PS/2 mouse keyboard plugs

    I just got a port replicator that enables plug and play PS/2 mouse and keyboard port. does anyone know if I can use a Y adaptor to plug into the PS/2 ports on the replicator and have 1 PS/2 port mounted somewhere with out frying the port replicator or the KB or the mouse. If the battery dies on my wireless KB or mouse, I can just plug either one into the PS/2 on the Y adaptor and get a working mouse or KB with out rebooting.

    Since no one knows, I built my own Y and pluged it in. It didnt work. My computer acted all crazy. The only way to get it to work is building a switcher out of a 4PDT relay. I still think its cool to beable to just plug in a mouse or a keyboard when your wireless runs out of battery as a back up.

      I had a circuit to do this on my PC, but Ive lost the HD's in that so nada

      Anyway, it was just a simple switch inline with to keyboards and a SPDT switch that switched the clock signal.
      I would think it is the clock Re-asuring huh?

      Here is some stuff pinched from the web:
      ------------------------
      The keyboard is free to send data to the host when both the KBD Data and KBD Clock lines are high (Idle). The KBD Clock line can be used as a Clear to Send line. If the host takes the KBD Clock line low, the keyboard will buffer any data until the KBD Clock is released, ie goes high. Should the Host take the KBD Data line low, then the keyboard will prepare to accept a command from the host.
      ------------------------

      This site has a circuit which will supposedly allow two keyboards at the same time, you could type one letter on alternative ones:

        To be on the safe side, I used a DPDT relay to switch the data and the clock. My switch is built and its working perfectly.
