I am starting to sound like a broken record, but here it goes. If you want a more complete tutorial on writing stack based virtual machines, check "The Elements of Computing Systems" and its accompanying course, http://www.nand2tetris.org/.

The book teaches you to build:

1) A CPU from basic electronics elements

2) An assembler to generate machine code

3) A bytecode VM that can be simulated and an assembler generator from the bytecode

4) A basic programming language that generates bytecode

5) An operating system using that language.

I'm midway through building the Assembler and VM myself :-).
