Is there a way of using two computers with one monitor , keyboard and mouse so that I can switch from one to the other? I presuming something like a usb cable would be used but I don't know if I would need software too be able to do this. Any advice would be appreciated. Thamks.
just as a little endorsement, I use the exact belkin product that Diodorus Siculus has linked to (although just to control the keyboard and mouse as i use three monitors for design purposes) and I would thoroughly recommend it.
it works perfectly with an XP system and 98se and there is no problem using a small convertor if you have an old AT style keyboard connector.
