I, unfortunately, didn't get the privilege of getting my hands on an assembly book. At 13, being inspired by the demoscene (I got the Unreal demo on a Simtel CD), I begged my parents to buy me Turbo Assembler. And I somehow thought that the included manual was going to be enough to get started (!). The manual had a great listing of Intel instructions, but I had no understanding of addressing modes, the stack, or what was required to make DOS system calls. Later, when I figured it out in college, I was mad because it was so simple and 13 year old me would have loved it. Unfortunately, at that time there was no internet, and the public library only carried books on high level languages. Argh. How I envy you. By the way, how did you figure out graphics programming?
