Your childhood interest in 80s computing is like the golden era of MMOs. Now there are bigger and "greater" things and the entire thing just seems poor and pointless now. You can't go back and recreate it, because the context is now different. It would be pure re-enactment. Back then it was the best thing about, if you didn't have an arcade near you then it was probably even the most powerful videogames machine you had access to. Now, there is always the knowledge that you will never make something as cool as what the big companies can make.
