That Minecraft CPU video from the article was amazing. It never would have even occurred to me to make such a thing.

  With the advent of pistons in the game, people have even added hard drives[0] by using a loop of glass (non conductive) and other blocks (conductive). [0] https://youtu.be/q7clz1TPK8o https://youtu.be/q7clz1TPK8o

    More accurately, delay line memory

      It's not a delay line though. It's linear access, sure, but you can decide when and if to step it.

        Shame on me for not watching the video then. I (rather short sightedly) though you were referring to a separate implementation that WAS delay line. That's a significant improvement then

    As an aside, when I played that game I once made an octal data tape, capable of reading 3 bits of state from a single block in the tape (the "loop"). Used three read circuits next to the tape, which allowed it to detect an additional three states; Namely the block could be non conductor, simple conductor, or a piston block facing up / sideways / down. From there, timing data is enough to distinguish a "sticky piston" from a regular one, allowing for 8 different states distinguishable to the read head. (Apologies if this is me-too ism)
