Inspired by @marcellanz’s thread here: "old" printed OTP documentation – Cover, I thought it would be nice to have a thread for those who’ve been involved with Erlang for a while and who’d like to take a trip down memory lane …do you have any stories to share? I’m sure I can’t be the only one interested

Unfortunately as far as I know there was no video. It wasn’t really a presentation as such, we were showing the train set as a demo of Erlang at a trade show. We thought that just showing a switch would be too boring and this would attract more people. I think there isn’t even a picture of the track we used in demo or the graphical display of the track with trains on it another colleague did.

Have to add this from our Hello World thread 
Thanks for posting all those photos @keyhan! I didn’t know there was an Erlang Swiss knife! Also curious about this one - what’s the story behind that?
How old was the pic with Robert and the train track? Not sure if you’re aware Robert, but pretty much everything you’re wearing is back in fashion now!! 
Maybe they were working on a very early GRiSP prototype?

thanks for opening this thread,
I designed that simple poster several years ago, it is about concurrency, real-time, and the reliability of erlang.
