Replace the whole computer from something bought off the web. The specs for I/O should still be available. Program it and get it up there. The hardest part would be creating some custom I/O (physical) ports to plug into the board, but software should be able to handle most of the interface work through them. Then shield it. Send up a SpaceX mission to do the swap. For the last 30 years chemical processing plants and other high tech facilities have been continually automating/computerizing. They have to fix and replace outdated PLCs all the time. This isn't anything all that different (if at all). In the real world, as opposed to universities, research, and NASA, this kind of issue is fixed fucking daily. So come on, this is a ridiculous issue to overthink. In fact, I'd give it to SpaceX to fix straight out. They seem to be the only ones looking at the idea of working in space as a routine activity. They said the rest of the unit is fine, so swap the computer and bring it back online.
Oh wow, look at you go, you outsmarted NASA and JPL. The environment in space isn't different from terrestrial environments at all. Just Amazon some PC parts to the space station. They'll work just fine.
Replace the whole fucking computer for fuck's sake. There must be design docs that show the physical I/O ports and their specs. I'd be surprised if they couldn't buy parts from NewEgg or Amazon that would work. Put them in a shielded box if need be but I think it would be stupid to try to over-engineer something that someone in a modern day chemical or other manufacturing facility could fix in a day or two.
Example of a modern day armchair scientist right here. Where'd you get your doctorate in aerospace engineering? How is over-simplistic drivel like this modded up?
Lots of people get banned on paypal every day, and we don't know anything about why it happened.
You say that like we should just accept it because, "that's just the way they are."
