# FastView-REA: a Rust reconstruction of Fast View 5

> A Rust desktop reconstruction of Mekhanotronika Fast View 5 uses REA and Ghidra research to reproduce oscillogram analysis and relay-characteristic views. The project publishes behavioral specifications, factual indexes, screenshots and cross-platform builds, with explicit format and visual-fidelity gaps.

## Requirements & limits

- **Prerequisites:** Source builds need the documented Rust toolchain; release archives target Linux, Windows and macOS. Linux needs GTK 3 and a Wayland or X11 session.
- **Testing evidence:** The README attributes the reverse engineering to REA and Ghidra 12.1.3. Its behavioral-identity and validation statements are author-reported.
- **Limits:** Native .sto input lacks a supplied sample, and the egui interface is not pixel-identical to original GDI/MFC rendering; original bitmaps are replaced.
- **License:** Reconstruction code offers MIT or Apache-2.0. Embedded fonts and Intel-derived trigonometry keep separate licenses; the bundled FastView.fvb characteristic data remains original-vendor data.
