I first started with a manual switchbox which I had to turn a knob to A or B, depending on the computer I wanted to use. It worked great, but I could only share a monitor between two computers and still had to use separate keyboards and mouse. My computer guru then purchased and installed an electronic one which had all the ports needed to share monitor, keyboard and mouse between two computers. I only need to hit my Control button twice to switch between the two computers.It has been working just great and I love the extra space. It's called MiniView KVM switch by Harding and it did cost $125 or so. The manual switch box was much cheaper ($50, I think). I would imagine you could find a manual switch box with the extra ports for sharing the keyboard and mouse, but I had a hard time locating one - hence the electronic version.
I believe my computer guy had to "network" my two computers in order for me to easily transfer work between the two computers but I don't think it would be necessary if you just wanted to run two computers separately but with sharing the keyboard/mouse.
If you can't find anything on the Net, try a local computer company and they can purchase it for you. Maybe with the above info, you'll find what you're looking for!
Good luck!
