For reference, the Hubble is running a "25 MHz Intel-based 80486" which is 34 years old. "The DF-224 and its 386 co-processor were replaced by a 25 MHz Intel-based 80486 processor system during Servicing Mission 3A in 1999. The new computer is 20 times faster, with six times more memory, than the DF-224 it replaced. It increases throughput by moving some computing tasks from the ground to the spacecraft and saves money by allowing the use of modern programming languages." https://en.m.wikipedia.org/wiki/Hubble_Space_Telescope https://en.m.wikipedia.org/wiki/Hubble_Space_Telescope The 80486 was introduced in 1989. I still have a couple. Three cheers for backward compatibility!
