+- Back to assembly… can we not? (kidding, but also not really.)
+- Input/Output- we have predefined registers out of the ram range?

+As with project03, this project with assembly language is starting to overlap with CSCI 306- working with assembly. Although I didn’t necessarily like that part of the course, I understand it, and I’m hoping that will overlap now. The only problem I see myself facing in the near future is shedding my RISCV assembly tendencies and learning hack, which seems to have weird syntax comparatively. Otherwise, the instructions from a high level here make sense and appear to be straightforward.
