Shout out to RS232, as an aside! One of my very first experiences with coding was communicating with devices over serial with RS232. 25 years later it's mostly usb-adapters and 5v TTL converters instead of the old school (in my day) db9 connectors. But I still use it all the time for hobby projects.
