Between 1988 and 1995 Jack Crenshaw posted on Usenet "Let's Build a Compiler", a tutorial series on writing a Pascal compiler that generates 68K Assembly. 35 years later Eli Bendersky revisited the series and rewrote the compiler in Python to generate WebAssembly.

Speaking of Jack Crenshaw's "Let's Build a Compiler", Ahmed Thabet reformatted the series and published a prettified and browsable version. Nice.
