CASA, the Classic Adventures Solution Archive, is a website dedicated to 8-bit and 16-bit text adventures and interactive fiction. The site was created in 1999 as a resource for solutions, maps and hints. In 2010, the site was expanded to be a database for adventure game information as well. As of this writing (October 2017), the site covers a little over 7,300 games. The main focus is on games for the popular 8-bit computers such as Spectrum, Commodore 64 and Apple II, but the entire range of 8-bit og 16-bit micros is covered (BBC Micro, Amiga, TRS-80, Dragon etc.). Modern IF is covered to a limited extent.
Apart from solutions, maps, hints, and game information, there are also manuals, interviews, articles and a forum.
