It's been a while since I've played the deep-space-microprocessor game,
so I'm a little out of touch. At one time, they were making them. Maybe
they came up with a better alternative?

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.
