Engineering Counter and comparator circuits connected

Click For Summary
The discussion focuses on troubleshooting issues with two circuit types involving comparators and counters, specifically using IC 85 and IC 393 on an NI ELVIS 2 prototyping board. The user reports that the waveforms obtained do not match expected results and seeks guidance on correcting the circuit connections. Despite sharing links to waveform results for both circuits, there is skepticism about the effectiveness of diagnosing issues solely through images of the breadboards. The user emphasizes the need for assistance in achieving the correct outputs for both circuits. Clear guidance is requested to resolve the discrepancies in the circuit performance.

Hi all, I need serious help here. I have to build two types of circuits as shown in the attached. The second one shows the circuit when the comparator's output is returned to the CLP. The IC's used here are IC 85 and IC 393 and the prototyping board used here is NI ELVIS 2. I think I have connected the pins right but the waveforms I got look so weird! I am required to get the results as in the last picture for the first circuit. In the second one, I am supposed to show that the counters are cleared. Please tell me what to do to correct this. Please do check my circuit. I have looked hard and I don't see anything missing.

Here are my results, I only did for N=6, though.

You don't seriously think anyone will be able to just look at pictures of your breadboards and figure out what the problem is, do you?

I just uploaded my result. Can you see them?
