Marbly Heart (Re: Looking for old computer book)

Hi Making the logic elements is easy, that hard part is making a useful size memory. Even for the logic, one has to make a system of amplification. A single marble offsetting a balance isn't useful unless it can be amplified. My thoughts were to have a mechanism similar to how a teletype works. Then idea is to have a lever that provides the power ( human ). It would push a dowel into a location that either had a mable or didn't have a marble. If there was on there, it would push through to another lever that worked the marble action one gravity level up where the next marbles were to provide other action. This way, a single marble could control the action on many marbles. Pulling the lever back would allow the selected mables to drop from the higher level to the bottom level where they would again be used to drive the top level logic action. Marbles would be feed into a hopper at the top of the machine to keep things running.
