I have three computers in my study. The most used are my Windows machine and FreeNAS machine. It would be really handy to be able to just have one keyboard and flick a switch as I need to use it for one or the other. I also have a Linux machine so a way of switching between three computers would be even better. Keyboard I have at the moment is a decent USB mechanical keyboard, and I'm thinking some sort of switchblock might be the best option if such a thing exists ? If it matters, the windows and NAS both have USB keyboard plugs but the Linux machine is older and only has ps/2 Anyway is there a solution to my first world problem please?
