The Jupiter Ace by Jupiter Cantab was a British home computer released in 1982. The Ace differed from other microcomputers of the time in that its programming environment used Forth instead of the more popular BASIC. This difference, along with limited available software and poor character based graphic display, limited sales and the machine was not a success.
