Nand2Tetris Questions and Answers Forum

If you have questions about Nand2Tetris projects or software, you are in the right place. Please select a sub-forum and review the posts; there is a good chance that a similar question was previously asked and answered. If not,  post your question, and we will answer it shortly. If you feel like answering some of the questions yourself, feel free. Please avoid posting solutions or solution segments (a few lines of code is fine). It's important to let people have the freedom to build the computer on their own.
