 In 2004, Tundra joined with IBM and others to form Power.org, an organization devoted to drive development and adaptation of Power ISA computers.Although Tundra was incorporated as an entity in 1995, its history goes back to 1983 as Calmos Semiconductor, which was subsequently acquired in 1989 by Newbridge Networks Corporation, where it became known as Newbridge Microsystems and in 1995 was spun out as Tundra Semiconductor.In June 2009 Tundra was acquired by IDT.
