The Jupiter Ace 4000. A rare vintage Home Computer released in 1982 by the British Company Jupiter Cantab. This example is in excellent condition except for small scuff/ mark on corner. See pictures for details. This is untested and only one lead. No power lead,but by looking at condition I'd say it would work as it sat in someone's drawer for years so it hasn't had much use. One's that are working with all the leads are priced up around the high £400's so I think I've priced this accordingly. At the end of the day it's still a rare Home Computer a must for any collector of vintage Computers.
