The main purpose of this page is to provide the support documents for products no longer supported by the company that originally produced them either because the company has ceased to exist or has left the RISC OS market. Many of these documents will also be linked to from the appropriate page under  Computers,,  32bit Upgrades,   8bit Upgrades  or  Software.


I acknowledge that most, if not all, of the documents on this page are subject to copyright. To minimise the copyright infringement (if such is possible), I will only place documentation for products that to the best of my knowledge are no long being active sold, developed or supported. If anyone claims ownership of the copyright of any of the documents on this page and objects to the document being made available here, please contact me and I will immediately remove it.

The Archimedean was Computer Concepts newsletter which was sent to users of Computer Concepts' Archimedes products. These PDF files are large, they contain the scanned page images and have not been OCR'ed because background colours and images makes it very difficult to get a reasonably accurate representation of the pages.
