CSC 215 Weekly Assignments: Week 5

CSC 215


I have two alternative plans for what we do next, which will depend on our feedback from the last programming assignment. We will decide together in class whether to spend a bit more time understanding the architecture of our computer, or moving on.

Friday, September 29th


Today we will take a first look at the book we will be using for the next phase of our learning, CP/M Assembly Language Proramming, but Ken Barbier.

Before we can begin using this book, however, we need to move from the online Altair 8800 simulator we have been using to a more full-featured one. Today in class we will take care of that.

Download LiamsAltairConfig.tgz, extract it and add the altairz80 program appropriate for your host operating system.


Read Chapter 1: Hardware Components Of the Computer System, taking detailed notes in our git repo in a file named


I will expect to see notes that indicate an understanding of the chapter content.

Today in class we will share our solutions to the programming problem given last week.


Write a program that reads a number from memory address 0x0047. If the number read is even, then it is replaced at the same location with 1/2 the number. If the number is odd, it is replaced with double the number.

Pairs for this assignment are: Julissa and Joseph, Cyrus and Sheel, and Nate and Edward.


This assignment is due before you arrive in class on Friday.
