 3. Select one person to be the "Driver", who will type/operate the computer for the group. That person should connect a device (laptop, table) to the HDMI display and open the [[6502 Emulator]] at [http://6502.cdot.systems] as well as this page. 4. Decide how group results will be shared between the members of the group. (Suggestion: consider using a git repository).

# 4. Paste this code into the emulator:

4. Test the code by pressing the Assemble button, then the Run button. If the there are any errors assembling (compiling) the code, they will appear in the message area at the bottom of the page. Make sure the code is running correctly and that everyone in your group understands how it works.56. Add this instruction after the <code>loop:</code> label and before the <code>sta ($40),y</code> instruction:

67. What visual effect does this cause, and how many colours are on the screen? Why?78. Add this instruction after the <code>tya</code>:

89. What visual effect does this cause, and how many colours are on the screen? Why?910. Repeat the above tests with two, three, four, and five <code>lsr</code> instructions in a row. Describe and explain the effect in each case.1011. Repeat the tests using <code>asl</code> instructions instead of <code>lsr</code> instructions. Describe and explain the effect in each case.1112. Remove the <code>tya</code> and all <code>asl</code> and <code>lsr</code> instructions.1213. The original code includes one <code>iny</code> instruction. Test with one to five consecutive <code>iny</code> instructions. Describe and explain the effect in each case. '''Note:''' ensure that the Speed slider is on its lowest setting (left) for these experiments.

14. Write code to draw a green line across the top of the bitmap screen and a blue line across the bottom.

15. Write code to draw a yellow line down the left side of the screen and a purple line down the right side.
