* Step 2b Lets make a Line text editor
Now I don't know about you but I suck at not making mistakes and having to fix a whole line instead of an entire file is a hell of an improvement.
So, lets make a line text editor, (it'll be 916 bytes long and require you to type 1,832 characters perfectly to make it)
You can build this file 2 ways:
1) Cheat and simply use stage1/SET.hex0 and run:
./bin/vm --rom roms/stage1_assembler-0 --tape_01 stage1/SET.hex0 --tape_02 roms/SET
or
2) Manually type in the contents of stage1/SET.hex2 (Minus the comments of course) while running:
./bin/vm --rom roms/stage0_monitor --tape_01 /dev/null --tape_02 temp
Then you can compile the text file with the stage1_assembler-2 that we already made.
From this point on I will assume you are going to take the easy route and simply load the source code using some mechanism you trust or are using SET to manually duplicate the entries of the code files used in each of the proceeding steps.

* Step 3 create a better hex assembler
Now that it is easy(ish) to create text files and we have a really stupid hex assembler, we probably don't want to manually calculate offsets and jumps any more.

* Step 5 Lets get us a line macro assembler
I don't know about you but at this point, I don't wanna convert another instruction into HEX by hand, so to save myself the pain we are going to write the most often ignored but important development in computer programming. The LINE MACRO ASSEMBLER.
