# 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. - Leverage native parallel subagent dispatch and 200k+ context windows where available. ## When to Use This Skill Use symptom -> action triggers: when one matches, apply this skill and verify with the protocol below. - User asks to create a breadboard layout or circuit mockup - User wants visualized component placement for legacy electronics - User needs diagrams for 6502, 555 timer, EEPROM, VIA, or 7400-series builds - User asks for educational electronics visuals or wiring diagrams - User is following retro-computing tutorials and needs visual references ## Prerequisites - Understanding of component pinouts from bundled reference files - Knowledge of breadboard layout conventions (rows, columns, power rails) ## Supported Components ### Microprocessors & Memory | Component | Pins | Description | |-----------|------|-------------| | W65C02S | 40-pin DIP | 8-bit microprocessor with 16-bit address bus | | 28C256 | 28-pin DIP | 32KB parallel EEPROM | | W65C22 | 40-pin DIP | Versatile Interface Adapter (VIA) | | 62256 | 28-pin DIP | 32KB static RAM | ### Logic & Timer ICs | Component | Pins | Description | |-----------|------|-----
