Potential articles for reference. Also need to check Drobe and research printed copies of Micro User, Acorn User, Archive, etc.

Note: Academic journals should be grouped together some time, for someone with access to a university library to look into!

  • I think that Iyonix is a separate company, and therefore won't be listed as a subsidiary.
  • Also, we could do with including a replacement for this official image, as it's presumably not free. (There are also five photos on the current website, but I can't see the article becoming long enough (in the short- to medium-term) to warrant a photo for each machine.)
  • Include PNG of Iyonix logo.

RISC OS

Logos

While under Acorn's ownership, the identity of RISC OS was integral to that of Acorn itself.[1] Previously, RISC OS used the Acorn nut device as its representative symbol[1], but that trademark (or a derivative of it) had subsequently been registered by Aristide & Co Antiquaire De Marques.[citation needed] After Acorn's demise, there was a need to establish a specific visual identity by way of a new logo.[1]

RISCOS Ltd's RISC OS 4 already had its own logo, a 3D cube.[1] Therefore, a new logo was designed by Richard Hallas, a former editor of RISC User magazine.[citation needed] His design was created with the intention of satisfying all of the following conditions:

  • It should be graphically simple, but yet have a complex enough shape to be recognisable at a glance.
  • It should be simple enough to be usable purely as a shape in monochrome, but with a more attractive complementary colour version.
  • It should be visually interesting when viewed at a large size, but still recognisable even if used at extremely small sizes (such as in the corners of file icons).
  • It should be usable in isolation or in combination with other text, just as the Acorn Nut could appear either on its own or at the end of the word 'Acorn'; in which case it must form an appropriately balanced whole.
  • It should be a regular shape which can easily be used within other designs and which is not greatly affected by questions of angle or perspective.
  • In its colour form, it should make use of few colours in order to avoid over-complexity, have impact, and be capable of being printed with spot colours for limited-colour printing. Notably, there was a flat green version of the Acorn Nut as well as the nice, shaded 3D version.
  • Whilst the question of being an abstract design isn't a problem (lots of logos are abstract), it should preferably be a fairly even shape; not too tall or thin. The Acorn logo was taller than it was wide, but only by a little; the Apple logo is more or less square in terms of its bounding box; the Windows logo is a rotated rectangle with roughly 4:3 proportions. These are all harmonious, flexible shapes.

Table of logo variants
