It was supposed to be sufficiently rad-hard and had its instruction set pruined for a higher level of determinism. I've not heard if a) it has made its way into production, b) found much acceptance or c) had an Ada compiler ported to it. The 1750 may still be the only available game for deep space at the moment. I had heard that Plessey stopped making their rad-hard version. (They kept threatening to do this unless we gave them more money.) I think LockMart may have one they build for themselves. The 1750 may be 1970's technology, but it seems to refuse to die - more from lack of a successor than anything else.
