"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."
Edit: Hmm... that's still only half the resolution mentioned in the article...
That would give a maximum arbitrary resolution of 8192 pixels in two colours. Not so good.
Anyhow, why didn't these fellows get sued for producing hardware so similar to Sinclair?:
The Jupiter ACE was a British home computer of the 1980s, marketed by a company named Jupiter Cantab and named after the early British computer, the ACE. The company was formed by Richard Altwasser and Steven Vickers, who had been on the design team for the Sinclair ZX Spectrum. ... The Jupiter ACE somewhat resembled a ZX81 in a white case, with black rubber keys like the Spectrum. ... The font of the character set was identical to that of the Spectrum ... the editor was like the Sinclair editor rather than the original Forth editor. ... Several words were borrowed from Sinclair BASIC. -- http://en.wikipedia.org/wiki/Jupiter_ACE

Not if you could change the character-images between horizontal "scanlines". (Technically, 1 character-line isn't a scanline as far as the display is concerned, but it's a pretty close analogy).
