I suppose I don't really need the serial and parallel port as I have an old T20 ThinkPad that is used exclusively for autoguiding. Bit of a bugger though when I want to hook it up to the internet. I have about 60 feet of network cable running from the modem out into the back yard. Doesn't that catch your feet by surprise some dark nights when walking around with bare feet. My wife thinks it's a very funny dance.
