    RW> I must have this confused. I have a Keyboard, Display and Mouse interface

   Are you by chance referring to what is called a KVM switch?  Keyboard Video   
   Mouse switch, which is a hardware device that swaps the common keyboard, video   
   and mouse between more than one computer.  Here I have a Rose KVM switch made   
   by the Rose company from Houston which swaps between four computers.  However,   
   KVM switches can actually be provided which swap between FAR more than four   
   systems!  The next step up the ladder is generally I think to 16 different   
   systems, and you actually,per what I think is correct with Rose, can go to up   
   to 256 different systems with just one keyboard, video monitor and mouse.  As   
   well, the more sophisticated stuff also will handle audio switching, plus   
   other hardware channel swaps as well.  In general this kind of stuff is made   
   for control of data centers which typically are made up of relay rack hardware   
   systems.  Mine here has four complete relay rack systems in the six foot case   
   next to me - all industrial grade stuff with even old pig iron linear power   
   supplies and so on..   
      
   Same setup sort of out at the 117/3000 remote site operation with not only the   
   computer stuff all relay rack stuff but the entire ham radio full KW   
   commercial transmitter and VHF interface stuff, plus all the hardware control   
   for the antenna array switching and directional control that is handled from   
   assembly language serial port switching techniques which also interface to all   
   the multiple phone lines and so on as well.
