Originally a private DikuMUD (called CopperDiku) server running at Copper.Denver.Colorado.EDU, the code was eventually released on December 15th, 1991.

Copper was an innovative iteration on DikuMUD which expanded the number of users to 50 initially, and introduced custom prompts (that supported the ability to display health/mana/movement points), as well as mobile code so that mobs could have MEMORY.

Copper brought with it new areas that became staples, such as the Drow, Desert, and Lost City.

Many features were instituted that were later taken for granted, such as WIMPY, outdoor rooms becoming dark after the sun going down, , mobs having aggressiveness based on character alignment, mobile infravision , and even the Max Mana of clerics and mages increasing when gaining levels.

While Copper's codebase use dropped quickly, it was responsible for bringing the MUD community MercMUD, one of the most popular Diku-derivatives ever.
