October 25, 2021 -  I have been idle on the LLTP for a little longer than I wanted but I have been doing a bit of mind games on where to go with the construction of this 4 bit no transistor processor. I am trying out my standard Light Logic Vactrol devices on a copper perf board and making the parts placement as tight as I can.  The follow images look promising and show the partial wiring of a one bit latching memory. So instead of a design that will take up the walls of my lab, the new reduced design will only take up a table or desk top or mounted on something like a motherboard.
