By definition, the space-processor business is a very small niche market. Nobody is going to sell a lot of a chip that will fit that niche. The best we could hope for is for someone to take a commercial processor and make it rad-hard. Of course there would still be weaknesses in commercial instruction sets. Maybe we'd have to learn to live with it. I'd be disappointed to see 1750 emulation on a 32 bit processor because I think that the industry should move into the new millenium and start building the infrastructure for the next generation. (Someone had to bite the bullet and build compilers for the 1750, eh?) But I suppose there are lots of legacy systems that need the capability, so it has a reason to exist.
