We followed the YouTube video and gave ourselves a command block, placed it with a button on it, and posted the mc86 initcode:
We clicked the button and received an enchanted book:
We followed the instructions and clicked each of the six links to generate my mc86 computer in our world:
Next, following the YouTube video, we pasted the challenge source code into the command block we created earlier and click the button:
This gave us a book and quill with 1,195 pages of instructions:
We then placed this book and quill into the Shulker Box:
We placed a button in the mc86 computer (as directed in the YouTube video) and and clicked it to run the challenge program:
This started playing two different sounds in some kind of pattern with pauses in between; a hoe till sound and a bell sound
Here is an audio clip of the sounds:
Given the name of the challenge, we assumed that these sounds represented dashes and dots. The hoe till sound sounded like dashes and the bell sounded like dots.
We took the recording listed above and played it back at 80% speed (my code copying days were long ago) and wrote down what I heard:
-.-. .-. .- ..-. - .. -. --. -- --- .-. ... . ..-. --- .-. - .... . .-- .. -.A quick trip to MorseCodeWorld.com and we decoded it:
This gave us the flag:
