Purpose: Minimal assembly

This step is about introducing assembly in the most minimal possible way I could come up with. I used a personal project I found on the Web, called F-4 minimal instruction set assembly. Also, just found a processor implementation in C.

Outstanding

1. The narrative of the study section needs to be completed and smoothed out. It is obvious which sub-sections are incomplete, as they have either a TODO or a single placeholder sentence.
2. The last subsection is likely to need branching off into its own step. There, I am figuring out how to motivate assembly in a very intuitive way, both top-down and bottom-up. We may have fun with that one.
3. The apply section has 4 exercises, but they are only sketched out. They need to be properly stated. The last two will require us to have the required program and function written. This is also going to be fun.
4. The present section has to be filled out. This is straightforward.

This could be a lot of fun. The current and only simulator is for Visual Basic and rather dated:

1. F-4.
2. F-4 simulator code. Also here.

Writing something like VisUAL but simpler would be an all-around worthwhile project. This processor implementation might be a good reference.

Purpose: Introduce the micro:bit assembly

Step 5 is minimally sketched out.

TODO

1. The study section narrative has to be coherent. Break down further, if necessary. A subsection should introduce at best only one new concept.
2. The apply section needs to be more concrete and have guidance. Naturally, we need to have exercises done and problems solved before we give them to students.
3. The present section needs to be filled out.
