This is not sure-fire, but I've found that if the big label on the back does NOT have the notice "contains copyrighted code..." that it's most likely an original version.

Hi, I was wondering if there's a surefire way of telling if an IBM-PC has its original motherboard, without opening the case. I saw one at the Salvation Army today and was considering dragging it home (though I decided to take another machine instead). The machine did have a cassette port in the back, with a femal DIN connector. Is this attached to the motherboard? The machine also had a full complement of cards in its slots, with lots of ports coming out of it. And a 3.5" drive that was poorly fitted into the case. I'm wondering if I should make a trip downtown sometime this weekend, with the car. Doug Spence ds_spenc(a)alcor.concordia.ca http://alcor.concordia.ca/~ds_spenc/
