fixed 2 bugs, and uploaded a Linux binary tested with a much larger truth table today. A full 4bit ALU with zero, and negative detection.  supports add, subtract 2's compliment, AND, OR and XOR as well as NOT A. additionally there are 2 NO operation Flag states HIGH and LOW which can be used to trigger other signals (or be replaced with more functions). I will be burning a EEPROM this weekend or next for testing. I uploaded the truth table and the Logism files if you would like to try out
