Indrema Entertainment Systems was a consumer electronics company famous for the Indrema L600 Entertainment System, a game console intended for independent game developers. Founded in 1999 by John Gildred, Indrema's goal was to create a video game console based on common PC hardware and the Linux operating system. The console would have been the only open source console on the market, as well as the only modern console to allow free software to be written for it.
