​‘Radiation hardened’ PlayStation chip guides probe to Pluto

The chip is the MIPS R3000 CPU; it was used in the original Sony PlayStation, which ran games from the Final Fantasy and Metal Gear Solid franchises. It is being used to control thrusters, guidance, and other systems in order to help direct the probe to Pluto. This particular chip is “radiation hardened,” Escapist magazine reported. While the PlayStation uses a 33 MHz R3051 CPU, the New Horizons spacecraft uses a 12 MHz Mongoose-V CPU.
