At some juncture, Motorola told us they weren't going to make those any more. They were suitable for bolting to the side of a really hot jet engine - I'm not sure about space. We used the Mil-Std-1750a because it was (at the time) the only thing RAD Hard enough to go into deep space - or at least RAD Hard enough and with a demonstrated record of reliability in deep space. (Gamma rays are considered "A Bad Thing") I don't know about the MC68k in that environment - if it was being jettisoned before deep space, then the Mil packaging might have been sufficient. But I'm not a hardware engineer and I only fake it badly on newsgroups. :-) MDC -- Marin David Condic Senior Software Engineer Pace Micro Technology Americas www.pacemicro.com Enabling the digital revolution e-Mail: marin.condic@pacemicro.com Web: http://www.mcondic.com/ "Dan Cross" wrote in message news:9kedbi$fb3@augusta.math.psu.edu... > In article , > > Really?
