September 19, 2020 - I decided that I need to start adding labels to the LLTP to indicate what is what. Even I will get confused later as I add more registers.
September 14, 2020 - Just a brief update of where I am with the LLTP project. I am currently matching up CdS photo resistors and making a batch of 80 Light Logic opto-couplers and those will be used to wire up four 4 bit registers. These will be used for the Program Counter, Instruction Register and the A and B input Registers for the Adder.
That's enough couplers for two 4 bit registers.
