Welcome to the TRS-80 Color Computer Archive!

This site is the result of an effort to preserve Color Computer software and documentation. I've been collecting Coco related files since 2002: cartridges, cassettes, virtual disks, ROMs, music, pictures, manuals, books, magazines, Radio Shack catalogs and more. I also scanned several manuals and books to add to my collection, which is now available to the Coco community.

Many thanks to Steve M. for his prodigious Rainbow restoration project and for providing numerous manuals to the archive!

Enjoy!
