Jumpstart Z80 Machine Code

In the beginning, there was darkness - and then, there was machine code. This book will teach you the ways of old, before programming languages were ever even invented. Specifically, we will be looking at the native language of the z80 processor. Coincidentally, Ti 83 class calculators use a z80! So, we will be looking at these calculators. Throughout this book, you will fundamentally understand how computers work at a wire-by-wire level. This can only be done via machine code. Think about some programming languages you know. As you are hopefully aware of, when you write code, it gets compiled into the machines native language. We are skipping that, and going straight to the native code. This has several benefits of course. Programming in machine code, you will... - Understand the processor, and calculator, thoroughly. Wire. By. Wire. -Build and design programs impossible for Ti-BASIC Programmers. Can you use a BASIC program to place code that activates after you leave the program? I'll give you a hint: you can't. -Learn to document code with ruthless efficiency. You are, after all, programming in another language!
