FW: VAXstation KVM switching

Hello, My name is John Bailey and I am an integtrator of data projection and display systems in Research Triangle Park, North Carolina. I noticed this board on a search for VAX info and thought you might be able to help with a problem I'm working on. I need to control several VAXstation 4000.60 machines with a single keyboard/mouse/monitor. The environment is a telecom network management center with limited space per operator. Do you have any suggestions or know of any hardware that would accomplish this? The regulars (Black Box, Cybex) are no help. If not, do you know if the machines will operate without a keyboard and mouse (once booted), or support multiple connects and disconnects of keyboard and mouse while operating. Any advice greatly appreciated, John B.
