# Legacy Circuit Mockups
A skill for creating breadboard circuit mockups and visual diagrams for retro computing and electronics projects. This skill leverages HTML5 Canvas drawing mechanisms to render interactive circuit layouts featuring vintage components like the 6502 microprocessor, 555 timer ICs, EEPROMs, and 7400-series logic gates.
## When to Use This Skill
- User asks to "create a breadboard layout" or "mockup a circuit"
- User wants to visualize component placement on a breadboard
- User needs a visual reference for building a 6502 computer
- User asks to "draw a circuit" or "diagram electronics"
- User wants to create educational electronics visuals
- User mentions Ben Eater tutorials or retro computing projects
- User asks to mockup 555 timer circuits or LED projects
- User needs to visualize wire connections between components
