so those interested can figure out what effort they can or may contribute to the project? Considering the comparable lack of complexity, it could be emulated on an Arduino Mega, Raspberry Pi Something like that would be great, then we could show people (instead of just telling them), "This whole truck is emulated in a $10 microcontroller." Surely there's a better way to explain and historically frame an important system than by belittling it. I mean, yes, we all know (and everyone with a pulse knows) that technology is advancing, and has always advanced. Surely there's a more respectful way to illustrate that than to say "look how much this sucked, it only takes THIS little piece of crap to do the same job!"
I'm not saying that is the ONLY way we'd explain it. One of many. Rest assured, we will tell the story of how and why this amazing computer came to exist. And stop calling me Shirley. :)
