A complete textbook on computer architecture and assembly language programming, as a website, in easy-to-digest pages.
What can you do with Vision BASIC? Pretty much anything you want to. Speed will no longer be a problem! Why? Because on it's own, Vision BASIC is VERY fast! But when you need to crank out even more speed, all you need to do is insert machine language anywhere you wish to. Yes, you can actually type machine language instructions right next to BASIC commands! You won't need to load in external machine language files, and you won't need to poke machine language code to memory. This is because Vision BASIC also doubles as an assembler – you can write BASIC programs with it or machine language programs with it, or a blend of the two!
Vision BASIC also includes a whole new batch of commands to help you realize your programming dreams! Need sprites? Vision BASIC's got you covered! Need sound and graphics? Yep, gotcha covered there too! Vision BASIC was designed to greatly minimize your need to POKE around with all those crazy registers. In fact, you might never need to POKE again! And if you find yourself needing a command or function that isn't available, you can simply create it yourself – by creating the needed subroutine and calling it by whatever name you choose to give it. These "user defined" commands and functions can be saved into separate files and added to your programs whenever you need them!
An 8-bit minicomputer with a fully custom architecture. Hardware schematics, software (firmware), and an emulator for testing.
8-bit data width. 16-bit address space (with banking). 8 general purpose registers (5 normal, 2 indirect addressing, 1 flag), 16 instruction RISC instruction set, port mapped I/O.
xBIOS is like a programmers version of DOS. With it you can easily access files from your programs without using Atari DOS. It is smaller than DOS and therefore saves memory in your programs. You can even run programs from as low as $0200, however $0800 or $2000 are more common.
Limitations
- New files cannot be created.
- Existing files cannot be extended in length.
- New directories cannot be created programatically.
CEmu is a GUI application that empowers users to write assembly and test it by compiling it to bytecode and executing it in an QEMU-based emulator. CEmu combines all the advantages of a basic assembly IDE, compilation and execution environment, by relying on the great libraries Keystone, Unicorn and Capstone engines in a Qt powered GUI. It allows you to test binary samples, check your shellcodes or even simply learn how to write assembly code, all of this for the following architectures:
- x86-32 / x86-64
- Arm / AArch64
- MIPS / MIPS64
- SPARC / SPARC64
- (more to come)
A framework used by penetration testers for building custom exploits for infiltrating systems. Written in Ruby. Comes with a large library of payloads and other nifty and fascinating tools. It's worth learning to use if you're serious about penetration testing or exploit development. Also, the cutting edge of attack technologies winds up coming out of the Metasploit project.
A list of all of the interrupts in the 32-bit x86 CPU architecture.
Someone fed ROM dumps from a couple of Atari games into distellamap and generated maps of function calls, with sprite dumps. Amazing, how simple games were back then...
A disassembler for Windows. One of the best in the field, and v2.0 just went beta. It's shareware, though it doesn't appear to lack any functionality if you haven't purchased it yet.
A list of tricks and methods for optimizing code written for the ATmel microcontrollers using GNU GCC.
A wiki dedicated to the Commodore-64 home computer.
An online reference for Intel 32-bit assembly language opcodes and mnemonics.
An online reference for Intel 64-bit assembly language opcodes and mnemonics.
An open source modular macro assembler that supports a number of CPU architectures out of the box and makes it easy to add new ones.
