Forgive my ignorance of computer hardware but why are such antiquated computers the only things available for space missions?

As long as the spacecrafts OS is tightly written, even a poor lowly Pentium 1 will have excellent performance. We are too used to horribly inefficient bloatware sucking the mips out of our desktops to really appreciate the awesome power of modern CPUs. I used to program 8085s and Zilog Z80s back in the 80s, and the modern chips are Star Trek technology by comparison.
