Let’s first look at the 74LS; a quick google search will yield the datasheet on the first hit: The parts would be: You might even need knowledge like this to even pass the interview He was also on uc IEC technical committee.
If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The 9 LEDs will blink counting in seconds particularly 9 seconds then it’s going to loop from the beginning to 74129 the counting again.
A number of resistors if need be A single or more capacitor if need be.
