Interesting story. Some design issues don't change! We were on Ethernet - old fashioned 10Mbs Ethernet (I think) with physical "taps" into a shared medium and terminators on the end. This is easy to remember as I recall the class doofus one day sitting there absently chucking an object up and down in his hand, while people angrily wondered why a whole string of Xterms weren't working. Duty programmer storms into the room and confiscates the item and plugs it in again. This same guy, a couple years later, manages to helpfully try to remove "." files from someone's directory while logged in as root, and manages to remove all of the honours students' home directories.
