 I want to lay out the basic building plans here, mainly about color and design choices where I can make it work.  Obviously, space limiting, I can't do everything, everywhere, but this will help.

 - The clock of the 74hc138's in the register module need to be hooked up to the inverted clock signal.
 - Hook up control lines for the ram in/ram out.  000 is disconnected, but 001-006 are connected up, where 001-006 are left-right.

+- Program counter off to the right of the program counter, not enough space currently.  
+- As per [this post](https://thecodingchicken.github.io/2025/05/05/program-counter.html) where I freaked out a little bit, I want to implement a reset breadboard.  It'll be triggered by something, perhaps an arduino.  In short, pushbutton -> arduino (iterates through every register, program counter, MAR, output devices), and sets them to 0.  That shouldn't be too hard.  Who cares about ram, because that'd be impossible.  The program should be capable of setting it as it requires.  [This link](https://x.com/i/grok?conversation=1919116958076956924) might have the original content, just for me ;-).  It'll have to override the eeprom, so I guess that'll be another master override somewhere.

 ## Continuing the register build
 
 I've setup the decoding logic for the registers, which will consist of two groups, ram in, and ram out.  The ram in is controlled by a [74hc138](https://www.mouser.com/datasheet/2/149/mm74hc138-303670.pdf) and two [74hc02](https://www.jameco.com/Jameco/Products/ProdDS/45188FSC.pdf).  The NOR gate is required to combine the control logic and the clock signal, otherwise there's no way to make it only work on the clock pulse.  Ram out is controlled by another 74HC138 and two [74hc04](https://www.jameco.com/Jameco/Products/ProdDS/45209FSC.pdf)'s, as the output on the 245's are active LOW.  
-I've decided on using yellow for control signals, and I guess gray for modified control signals.  Plus, more colors is more better, right?  I've started a document where I organize all of that [here](https://thecodingchicken.github.io/2020/01/01/color_design.html).  I also have the one with stuff to print out [here](https://thecodingchicken.github.io/2020/01/02/stuff-to-print.html)
