That world doesn't exist anymore. Computers in the 80s was far smaller a field and had less societal impact. Today, pretty much every human in the developed one has access to a computer (a cell phone). The ecosystems are lot more closed today than they used to be. I like what the other person posted (webpage) but it isn't obscure. I'd say compiling your own Android image and putting it on a phone.
