I glanced through it. I didn't learn anything new, except the definition of bloat. The raw source wasn't available when I was doing this, so I learned it entirely by reverse engineering, and documentation. Ironically I learned how the boot sector worked and basic ASM purely by using DEBUG.EXE. My computer got infected by Stoned virus, and I was pretty excited about it! This was back when DOS came with a green binder with actual documentation. It was a year or so of that before I discovered TASM and then MASM assemblers, which of course are a LOT more human-friendly. The earlier versions of DOS were entirely written in ASM, and they were super-tight. But later versions were all rewritten in high level languages. The stuff in the leak is all the bloated high-level language versions.
