Interesting! I grew up before network cards was a thing in home computers (Commodore 64 and Amiga), but a group of my friends organized what we called «meetings» which I would characterize as your traditional LAN party. I remember at some point that we hooked up two Amigas over a fairly long parallel cable and were able to send data across. Cannot recall if we actually were able to copy larger files between them though. Fun times!
