> expensive, unfamiliar, specialized hardware when you can instead use cheap, well-known, store-bought CPUs that everyone is familiar with My impression (from wikipedia) is that several popular radiation-hardened CPUs are just embedded CPUs with a different manufacturing process. They should be as familiar as traditional embedded CPUs, just old and expensive. For example RAD750 is based on PPC750 which can be found in older macs.
