Oct 1, 2025Concise monthly summary for 2025-10 focusing on delivering user-centric features and improving maintainability for the Adafruit Learning System Guides repo. Delivered a visual logic gates simulator for Fruit Jam with core simulation logic, gate and I/O entity definitions, and an interactive workspace; included a minor refactor to improve readability. Implemented DOS disk image management for the 286 emulator, adding and reorganizing disk images (e.g., fdd0.img) and updating file structure to reflect the current emulator configuration. These efforts reduce time-to-value for users and streamline asset management for maintainers.
