## Overview
|
||||||
|
|
||||||
|
GameCathode is a hardware maker project that gives a second life to a Minerva MT 5511 CRT television found at a workshop cleanup. It was gutted and retrofitted with a complete salvaged PC, delivering pure analog video output directly to the original CRT tube — zero input lag, pixel-perfect retro aesthetics, no new parts purchased.

## Project Highlights
|
||||||
|
|
||||||
|
### 1. Pure CRT Experience
|
||||||
|
No digital-to-analog HDMI lag. The system outputs a native analog signal via the Nvidia GeForce 7300 for pixel-perfect retro aesthetics. Every scanline, every phosphor glow — exactly as developers intended.
|
||||||
|
|
||||||
|
### 2. Heavy Emulation
|
||||||
|
The Intel i7 provides enough overhead to comfortably emulate demanding systems like **GameCube via Dolphin**. Titles that would choke a Raspberry Pi run without breaking a sweat.
|
||||||
|
|
||||||
|
### 3. 100% Recycled
|
||||||
|
Every component was pulled from obsolete hardware destined for landfill. Proof that obsolete tech still holds immense value when reimagined.

||||||
