The Beginning of AArch64 and x86_64

Yesterday in class, we were introduced to AArch64 and x86_64.

To be honest I wasn't even caught up with 6502 labs, so learning more advanced Architectures without sufficient background knowledge of 6502 was very concerning.

But after first contact, I was kinda excited because both AArch64 and x86_64 has more available general-purpose registers and has commands that accepts more than 2 arguments.
This would make future labs (maybe lab 5?) more interesting to code, even-though I still haven't fully figure out lab 3. (I am stuck)

As for Lab 3, I started to look at other people's example codes for guidance.

Many of my classmates doesn't have proper coding for lab 3, it was a bit relieving that I am not the only one stuck.

Course Project Stage 2 Introduction

Issue has arrived!! Since I pushed my work for SPO600 till today because of my other focuses in other school works (my own fault), an issue has arrived. Today unexpectedly all the school remote machine rejected all my attempt for connection. A few days ago, there was an email send from the professor talking about all the machines are going through mass restarts on Friday. We were told to expect Aarchie and Israel might continue to be unavailable even after restart because the restart is done remotely. But today I wasn't able to connection to Bbetty and Xerxes as well which are the only other machines I have access to. Now, I have no choice but resort to one of my last resorts. I'll have to enable the windows subsystem for Linux on my laptop and work from there. Since I don't use my laptop for anything other than school work, this will keep my bench marking and profiling errors to minimum. My laptop system type is 64-bit OS, this would cover at least the Aarch64 part of
