the Jupiter ACE somewhat resembled a ZX81 in a whiten outbreak, by owning melanise rubber keys like the Spectrum. It displayed output in the televisiin, & computer software can be redeemed & loaded on cassette tape, as was standard at that instance. A machine come by using Leash KB RAM, expandable to 49 K. When it got simply 1 streaming mode, text simply, which displayed Twenty-four rows of 32 columns of characters around black & white, it was conceivable to display graphics, by redefining a 8×8 pixel bitmap of any of the 128 characters. Such as a ZX Spectrum, a machine's audio capabilities were restricted to bleep of programmable frequency & duration, output across the little built-inherent speaker.

Although a devices, & to a bit of extent a computer software, of a ACE was similar to the ZX81 & particularly the ZX Spectrum, unlike people machines it used distinct transistor-transistor logic logic rather than the ULAs of the Sinclair machines. A font of a character placed was monovular to it of a Spectrum, however once more unlike the sooner machines, the display was white in black. Unlike a ZX81, a display was generated by devices. Such as a Spectrum, a keyboard was of the 'chicklet' kind, however there was there is no only-keyword entry. the instance & speaker were as well super similar, although there was an additional interface for the attachment of a colour graphics board that was never produced.

A major difference from either a 'introductory computer' that was a ZX81, even so, was that a Jupiter ACE's designers, from either a get-go, meant a machine to exist as for computer programmer: a machine come using Forth as its default programming language. A accent of Forth river utilized on the ACE was according to Forth-79 like than FIG-Forth, although it deviated somewhat from either it within various ways. Particularly, screens were non utilized & a editor was like a Sinclair of these rather than a original Forth editor. Besides, many words were borrowed from either Sinclair Basic. Though Forth river gave a great speed benefit across a taken BASIC that was used within more machines, it did, along by having the meagre healthy & graphics capabilities in comparison a coming competition, keep a ACE squarely in a niche market. Gross sales of the machine were never super big; when of the early 2000's, living machines come quite rare, fetching quite high numbers when collectors things.
