Released in 1982, the Jupiter Ace is a fascinating little computer. It's hardware isn't much to write home about. It's just an 8-bit microcomputer very much in line with other systems of the era. Where it shines is it's software. In a period when most home computer ran some version of BASIC the Ace was using Forth. On the surface that might sound like a trivial difference, but that one deviation from the norm made all the difference in the world.   Selected Sources:   https://www.theregister.com/2012/09/21/jupiter_cantab_jupiter_ace_is_30_years_old - The Register article on the Ace   https://jupiter-ace.co.uk/documents_index.html - Every other Ace resource you could ever want
