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

[edit]

Logos

[edit]

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.
    — Richard Hallas, 'Rebranding RISC OS' article, on RISCOS Ltd's website[1]

Desktop

[edit]

The WIMP interface incorporates three mouse buttons (named Select, Menu and Adjust), context-sensitive menus, window order control (i.e. send to back) and dynamic window focus (a window can have input focus at any position on the stack). The Icon bar holds icons which represent mounted disc drives, RAM discs, running applications and system utilities. These icons have context-sensitive menus and support drag-and-drop behaviour. They represent the running application as a whole, irrespective of whether it has open windows.

The GUI is centred around the concept of files. The Filer displays the contents of a disc. Applications are run from the Filer view and files cam be dragged to the Filer view from applications to perform saves. Application directories are used to store applications. The OS differentiates them from normal directories through the use of a pling (exclamation mark) prefix. Double-clicking on such a directory launches the application rather than opening the directory. The application's executable files and resources are contained within the directory, but normally they remain hidden from the user. Because applications are self-contained, this allows drag-and-drop installation and removal.

The outline font manager provides anti-aliasing of fonts, the OS being the first operating system to include such a feature,[1][2][3][4] having included it since before January 1989[5] The RISC OS Style Guide encourages a consistent look and feel across applications. This was introduced in RISC OS 3 and specifies application appearance and behaviour. Acorn was criticised by some for not updating its own applications to comply with the Style Guide.[citation needed]
