The Epyx 1984 Preview Disk is one of the most interesting disks in my Commodore 64 collection. Not only is it a very early example of a video game company releasing playable, cut-down, or time-limited preview versions of its games, which later became an industry standard, but it's also a rare example of a Chromadisk, a unique manufacturing process that allowed full-colour printing directly on a disk jacket. This process, developed by a San Jose, California company called Memron, allowed each disk to potentially be a work of art, rather than just another black disk with a label stuck to it. In this video we'll uncover the story of Memron, and then look at the preview game demos on this particular Chromadisk, which include Epyx's smash 1984 hits Impossible Mission and Summer Games, along with some other lesser-known games. Finally, we break out the Super Snapshot machine language monitor and attempt to disable the 90 second playable time-limit on Break Dance.
