Inspiration：
Class 1800 was initially designed to replicate the retro appearance and layout of the G80-18xx as closely as possible while incorporating modern customizable internals and functionality. However, we felt that simply having an aluminum 1800 might be too safe and somewhat boring, especially since some friends have already released similar works. Therefore, we added a minimalist, interchangeable magnetic module design in the top left corner, offering a relatively simple retro-style electromagnetic buzzer module and a more complex dual-knob module for enhanced features.
