Unexpected Behavior (Clock, Reset, Programming Interface) #12

Hi! I believe I have been able to successfully program the Flash as well as the ATMega for the programming interface, but I am unable to understand why I am getting the results I am currently. Here is a video of what I have so far: https://imgur.com/a/B3an2lI

As you can see in the video, one of the first issues is that the clock doesn't seem to work. When I try to switch it on, nothing seems to happen. The pulse button does work (sometimes).

The next issue is that the reset button for some reason doesn't clear the C register.

And finally, the programming interface doesn't do anything (from what I can tell), since none of the LEDs are lighting up indicating it is programming.

Do you think that these issues could all be caused by incorrect programming of the AM29F040Bs? I was able to use the FMPUno and it seemed that they were programmed correctly when I read the contents.

Thank you for your reply. I have checked all of the ICs and they seem to be the correct way, and I am fairly confident that my soldering is also clean. The only thing that I think could possibly be wrong is the direction of the switch used to turn the clock on/off, but even that I am fairly certain is the correct direction.

I will take a look into the eeproms, but do you think the eeproms could really be the reason for malfunctioning clock? I also agree that clock should be working no matter what, which is why I am confused.

Also, could you please provide the name of the programmer you used (or perhaps a suggestion to one that might work)? From what I am seeing so far it may just be unreliability of programming the eeprom with arduino.

Thank you again for your help.

I am fairly sure that it had to do with the eeproms. Many of the control logic leds seem to be fluctuating and I am still unable to get the clock to work even with replacing all of the ICs. Could you please share the name of the programmer that you used, or perhaps recommend an official programmer?
