World of Spectrum
World of Spectrum (WoS) is "the official world archive for the Sinclair ZX Spectrum". Anything you might want to know about the Spectrum is more likely to be found at this site than anywhere else on the internet. This large archive of games, screenshots, emulators, utilities, documentation, magazine scans, links, etc. also boasts a forum and on-line chat system. The site is copyright 1995 to the present day by Martin van der Heide, ThunderWare Research Center, and is maintained by a large number of volunteers.
After a controversial site redesign in 2020, an alternative archive called World of Spectrum Classic was created, with the same content. Spectrum Computing is another version of the archive. Both present files at the same relative paths as the original World of Spectrum site.
