Nostalgia: It is doable for simple networking, at least. Dave Lyons did
this for his high school (West High School, Iowa City, IA) in the
early-mid 80's. A room of Apple II computers sharing one or two serial
printers through a simple serial interface using the 16-pin IO port. (At
least that is how I remember it.)
