Issue with serial communication
My Gigatron has an issue where the left arrow does not work on both the controller and the keyboard. Also, when I tested the keyboard many of the keys did not output their corresponding letter and some were even duplicates (I have two keys that output '7' for example). I checked for bad soldering, but I did not see any obvious problems. What are your opinions for what could be causing this?

This would be the connection of the shift register U39 pin 1 to the data bus. It can be checked with a multimeter. For example verify that this pin makes a connection to U10 pin 9.
