I went to a ramen place in Tokyo and to order ramen you had to insert money and place your order via this machine. This felt like going back to the early 90s but in a way that we are definitely not used to in western countries. It had a very retro futuristic vibe!
If you’re into learning about history and inner workings of retro electrical components, Fran Blanche has a great channel on YouTube! Personally, the nixie tubes and other retro displays/indicators are my favorite.
