Read the readme, consider myself a mostly-not-total-idiot. Would buy author a beer to add a whole two sentences to illuminate what wozman is. If it's just that niche and I'm ignorant feel free to ignore me.

Ben Eater has a number of very informative videos on Wozmon on YouTube - what it is, how it works and and getting it to work on a home built 6502 machine, literally stepping through the assembly:

It's a monitor by Steve (woz)niak.

Self explanatory really!

This might be helpful… https://www.youtube.com/watch?v=SpG8rgI7Hec I find it a little weird that these comments always come up on hackernews… if you type "wozmon" in your URL bar and hit enter to search, pretty much _all_ the results are pertinent and helpful.

I understand what this is. What I don't understand is what is the purpose of doing it.

fun?

That was the primary reason - a fun weekend project converting 6502 Assembly to x86-64 line by line. The x86-64 version comes in at a 384-byte binary due to instructions being a bit longer.

Good point! I've added some text about wozmon to the README.

It's the boot ROM that came with the Apple I. It was pretty big for the time given that in those days, computers didn't come with flash, so you had to bootstrap programs with dip switches and the like. The Apple I came with wozmon on ROM, which provided a (VERY) minimal prompt to edit/view memory and run programs from it.
