A Forth shibboleth is that you have to implement your own in order to understand it. Try reading the assembly, then forth source, for jonesforth: https://github.com/AlexandreAbreu/jonesforth This is how I learned.

In Collapse OS – Why Forth?

I feel like this might still be too high level. A better approach may be to teach by the example of writing a basic FORTH environment from machine instructions, then basic helpers written in the language, and working up from there. Various types of better things can be added in once there's something to optimize.

"" rsaarelm on Jan 28, 2017 [-] Working through Jones Forth got me up to speed on both understanding how Forth works and getting my hands dirty with some practical assembly coding. Once I got a better idea of Forth, I also realized that Jones stays in assembly for rather long. He builds up the entire interpreter from raw assembly words, because you need the interpreter to start parsing textual Forth source. But you if you could somehow write Forth before the interpreter is put together, it would be quite natural to switch to Forth much earlier. And it turns out you can do that. Jones even defines the `defword` macro. But for some reason he makes very little use of it. Rewriting most of the code leading up to INTERPRET using defword was a fun exercise. The next step would've been making the whole system bootstrapping by rewriting the assembler in Forth, but x86 machine code generation is hairy enough that I bailed out at this point. ""

In Thought Experiment: An Introductory Compilers Class

Your idea for a foundation of practical computing sounds a lot like MIT's 6.004 Computation Structures [1], which is available on OpenCourseWare and edX. In 6.004, you start by learning about the digital abstraction and MOSFETs, then go on to logic gates, flip-flops, pipelining, instruction sets, and halfway through the course you use a circuit simulator to build a RISC processor called the Beta. Then you go on to I/O buses, virtual memory, and interrupts, and at the end of the course you can compile C programs for the Beta. To get from having a processor to having a self-contained programming environment, you could work through a variation on jonesforth [2]. (You'd have to port it from i386 to the Beta if you wanted to keep the same architecture.) [1] https://ocw.mit.edu/courses/electrical-engineering-and-compu... [2] https://github.com/

This is a more interesting question that it might seem. For a Sunday afternoon read, please take a look to Jonesforth [1] for an implementation of a basic Forth for Linux/32 bits. It's written in literate style and it reads like a nice book. If you are not that interested in the implementation of the compiler (and if so you might be missing the ultimate point of Forth), Starting Forth [2] is a classic resource.
