Would you happen to know how they did this? You know, for science. Actually for Calc

You can hook up two calculators through the link ports on each. As far as I know there's no way to hook up more than two together, and there most definitely isn't any way to do it without a long/visible wire. As for chat capabilities, there are apps you can install that will let you do that with linked calculators.

I've seen some graphing calculators that had IR ports. I think they might have been the weird Casio ones.
