Encyclopedia > Jupiter Ace

The Jupiter ACE was a British home computer of the 1980s, marketed by a company named Jupiter Cantab. The company was formed by Richard Altwasser and Stephen Vickers, who had been on the design team for the Sinclair ZX Spectrum. The home computer is a consumer-friendly word for the second generation of microcomputers (the technical term that was previously used), entering the market in 1977 and becoming common during the 1980s. ... // Events and trends The 1980s marked an abrupt shift towards more conservative lifestyles after the momentous cultural revolutions which took place in the 1960s and 1970s and the definition of the AIDS virus in 1981. ... Jupiter Cantab Limited was a Cambridge based home computer company. ... Sinclair Research Ltd was a home computer company founded by Clive Sinclair in Cambridge, England. ... The Sinclair ZX Spectrum was a small home computer released in the United Kingdom in 1982 by Sinclair Research. ...


The Jupiter ACE somewhat resembled a ZX81 in a white case, with black rubber keys like the Spectrum. It displayed output on a television, and programs could be saved and loaded on cassette tape, as was standard at that time. The machine came with 3 KB RAM, expandable to 49 K. While it had only one video mode, text only, which displayed 24 rows of 32 columns of characters in black and white, it was possible to display graphics, by redefining the 8×8 pixel bitmap of any of the 128 characters. Like the ZX Spectrum, the machine's audio capabilities were restricted to beeps of programmable frequency and duration, output through a small built-in speaker. The Sinclair ZX81 home computer, released by Sinclair Research in 1981, was the followup to the companys ZX80. ...

For the use of the term raster in radio regulation, see frequency raster. ...


The major difference from the 'introductory computer' that was the ZX81, however, was that the Jupiter ACE's designers, from the outset, intended the machine to be for programmers: the machine came with Forth as its default programming language. Though this gave a great speed advantage over the interpreted BASIC that was used on other machines, it did, along with the meager sound and graphics capabilities compared to the upcoming competition, keep the ACE squarely in a niche market. Sales of the machine were never very large; as of the early 2000's, surviving machines are quite uncommon, fetching quite high prices as collectors items. Forth is a programming language and programming environment. ... BASIC is a family of high-level programming languages. ...

Jupiter Ace review. Your Computer November 1982 (2371 words)
THE JUPITER ACE is a radical departure from the mainstream of microcomputing, and could prove to be the start of a very important new trend.
Speed implies heat, but there is not much danger of the Jupiter overheating, or at least a sight less danger than some machines, because inside that flimsy plastic case is plenty of breathing room and what is more, the case is better ventilated than that of the ZX range.of computers.
Probably the biggest advantage of the Ace's picture quality over the ZX-81's is that the Ace has a rock-steady fl screen on which any printing appears in white: the ZX-8l does the reverse which is not a natural way for a computer to behave.
