I designed this simple unit myself but later learned that it had been already published before by Jose Arley Moreno. From a Facebook discussion I know at least one other person has come up with it independently as well (I don’t remember the details, unfortunately).
The name found on the original instructions uses the name “Modulo J.A.” (J.A. as in Jose Arley?). I’m not sure if I came up with the name Moreno’s Unit myself or saw it used by others somewhere.
This unit is in many ways similar to Sonobe.
