In 2014, Unisys phased out its CMOS processors, completing the migration of its ClearPath mainframes to Intel x86 chips, allowing clients to run the company's OS 2200 and MCP operating systems alongside more recent Windows and Linux workloads on Intel-based systems that support cloud and virtualization. The company announced its new ClearPath Dorado 8380 and 8390 systems in May, 2015. These new systems allowed the company to transition its ClearPath server families from proprietary complementary metal oxide semiconductor processor technology to a software-based fabric architecture running on Intel processors.
