- Yes, you can implement a few logic-like elements without electricity.
- Logic gates are primarily implemented using diodes or transistors acting as electronic switches, but can also be constructed using vacuum tubes, electromagnetic relays (relay logic), fluidic logic, pneumatic logic, optics, molecules, or even mechanical elements. Now, most logic gates are made from MOSFETs (metal–oxide–semiconductor field-effect transistors).

- Announcements
* Due to the instructor's significant involvement in a confidential project, there has been limited participation in this course. Consequently, the instructor proposes a modification to the course grading structure.
- The new breakdown will be as follows: Quiz (30%), Homework (30%), Final/Term Project (25%), and an additional "Base" component (15%). This "Base" component ensures that each student's starting score is at least 15%.
* Quiz7 is scheduled on Jan 7, 2024
- [rv32emu](https://github.com/sysprog21/rv32emu) introduces tier-1 JIT compiler to accelerate RISC-V simulation.
* Execute `make ENABLE_JIT=1 clean all` and then run `build/rv32emu build/smolnes.elf` to play NES games.
