A technical history of Acorn Computers (Version 0.6 Beta)

These pages contain a fairly brief technical history of Acorn Computers. I have decided to focus on the technology because that is where my interests lie. Only very major non-technical events in Acorn's history have been included. If anyone finds any inaccuracies in the following pages please contact me using the link at the bottom of the page, including a correction if possible.

Note that the information on these pages is not an offical history of Acorn's computers and has no official support from Acorn Computers.

These pages are under construction. I'm very busy at the moment, but I'm trying to sort these pages out as quickly as possible.

19th April 2004 - a few days late, but never mind... Happy Birthday, RiscPC! (10 years old on the 16th of April.)

There are some gaps in this history. For example, I know that there was a PocketBook II released by October 1996, but I don't know how it fits in. Also, I don't know very much at all about the Acorn Network Computer, Set Top Box 2, Stork or NewsPad, and I can't remember when the StrongARM was transferred to Intel. I also don't know very much about the post-Acorn RISC OS machines, the R7500 and the Mico, among others. Any information on any of the reorganisations (in 1995/6 and 1997, I believe) would also be appreciated. If anyone can supply any information, or point me in the direction of some information, please e-mail me using the contact link at the bottom of the page.
