Eros One was manufactured under Fascination with Allied Leisure parts and original design. Allied first released their own version "Flame of Athens" before them within a year apart of each release.
Allied Leisure designed a CPU board similar to Bally's HUO idea. Using microchips capable of storing ROM with its integrated RAM and PIA capabilities, it allowed the CPU to work with a condensed version of a typical microcomputer amid everyone sees in commercial pinball machines and video arcades. Its similar programming reacted like an electromechanical machine.
This game uses the Allied Leisure System 3 board (beige).
