Here are a few of my assembly language projects that I completed as practice and for an assignment on computer architecture and organization that I thought could be useful to you. I used the educational computer model called The Little Man Computer (LMC). Quick instructions to run:
Open https://peterhigginson.co.uk/LMC/
Copy the content of the code file
Paste it into the left-most box of the Little Man Computer site
Under "OPTIONS", set the default speed to fast
Click "RUN"
Enter a number
