Dungeons of Daggorath is one of the first realtime action first-person perspective role-playing video games. It was produced by DynaMicro for the Tandy (RadioShack) TRS-80 Colour Computer in 1982.
The game was written by Douglas J. Morgan and Keith S. Kiyohara, with sounds by Phil Landmeier, in 1980-81. It was released as a ROMpak cartridge for the Colour Computer, which limited the size of the code to eight kilobytes, which took several months of recoding to achieve. Despite this, the game features a multi-level maze and has what for the time were advanced sound effects that provide important clues to the location of the first gate.
