This article is from the comp.sys.acorn FAQ, by Paul Vigay with numerous contributions by others.
As I frequently update the FAQ between postings you may wish to get the latest and most up-to-date copy of the FAQ before it next gets posted. There are two ways to do this. Firstly read it off the web at http://www.vigay.com/csafaq/
Secondly, if you don't have access to the world wide web I can email you a copy. However, in order to save my phone bill, I would prefer people to download it from my web site. I hope to set up an email server at some point in the future, which might make things easier.
