Working with the National Archives, Longlife Data Ltd have created a web version (compatible with IE, Firefox and Netscape - it's not happy with current RISC OS browsers) providing most of the maps, text and photographs from the community discs. They haven't preserved the original BBC interface, instead implementing a groovy four panel window allowing various bits of content to be displayed simultaneously. The second disc (The National Disc) which contained photo galleries and virtual reality walkthroughs is still unavailable.
Neat.
