I.$-$ Objective Suppose a small program is permanently stored in the last few mailbox locations. A BRANCH instruction at location $00,$ also permanent, will start this program. This program will accept input values and will store them at consecutive mailbox locations, starting with mailbox $01.$ You may assume that these values represent the instructions and data of a user's program to be executed. When a $999$ is received as input data, the program jumps to location $01$ where it will proceed to execute the values just entered. The small program described here is known as a program loader, or$,$ under certain circumstances as a bootstrap. This program takes advantage that instructions and data are indistinguishable $($Von Neumann architecture$).$ Thus, instructions could be treated as if they were data, if necessary.

Follow from here by looking at the attached picture.

II$.-$ Make a report that should include:

$1.$ A flowchart of the program loader program. Make sure you explain well what is that you are doing in the flowchart, otherwise you will lose marks.

$2.$ The code that you have used to load the program loader starting in memory location $86.$ Explain in detail how it works.

$3.$ The code for the modified program loader that starts at mailbox $00.$ Explain the changes you had to do and why you did them.

$4.$ Present and explain your work in points $1,2$ and $3$ of Section II

$5.$ A picture of the LMC running the original program loader and showing the user program being loaded and executed.

$6.$ A picture of the LMC running the modified program loader and showing the user program being loaded and executed.
