I'm grabbing at a single point here, but this really jumped out at me: > Solutions that work great on your computer might fail completely in the field running on a 486 with a radio internet connection. How common is this sort of thing in the field? I've read the "popular" stories about old C64s and Amigas still being used to do things, but not enough real-world data surfaces to be able to build a realistic/practical/robust mental model of what to expect. I'd fully expect old equipment in eg an industrial control context, but besides that it might come as a surprise. By the way, what sort of "radio connection"? APRS?
