One might expect cutting edge NASA space exploration equipment to feature some of the most modern technologies available. While that understanding might be true with regard to materials science, propulsion, cameras, sensors, and other important space exploration equipment it surprisingly isn't in terms of the computer chips used by the likes of the Mars Perseverance rover. According to a recent report from New Scientist the Perseverance rover uses the same single-core 233MHz CPU that powered the bulbous multicolour iMac G3 which started shipping in 1998. Specifically, the Perseverance rover is said to be powered by a single board computer (SBC) called the RAD750. This board is made by BAE systems and features a variant of IBM/Motorola's PowerPC 750 chip plus supporting components which work in extreme environments – it is hardened to withstand from 200,000 to 1,000,000 Rads and temperatures between −55 and 125°C.
