Hi,
If anyone's interested in my summary of the COS221 textbook (49 pages), you can download it from my
website. Also up there are some sample Assembly programs that I wrote, while trying to get to learn this new language

They start out quite simple, with programs that show you how to print characters to the screen and display input from the keyboard, and move on to some really interesting problems, like finding the first 1000 prime numbers and changing the time of your computer clock! There are detailed ;comments; and notes on the important / difficult parts. Hope they help you...
There are stacks of notes for other modules up there as well. Please help to build up the collection by uploading any Unisa notes you have that you have found useful.
