## What it is
MNT VA2000 is an open source graphics card for Amiga 2000/3000/4000 computers, implemented in Verilog for a Xilinx Spartan 6 FPGA on a Zorro II/III expansion card. The repository contains the FPGA firmware, KiCad schematics, and reverse-engineered Picasso96 driver support.

## Use cases
- add high-resolution graphics to an Amiga 2000
- build an open source Zorro II graphics card
- study FPGA-based retro graphics hardware in Verilog
- run Workbench at 1280x720 on classic Amiga hardware
- customize or fork an Amiga RTG graphics card design

## When to choose
- you own an Amiga 2000/3000/4000 and want modern display output
- you want to study or modify open source FPGA graphics card firmware
- you need Picasso96-compatible RTG drivers for classic Amiga

## When to avoid
- you need a graphics card for modern PCs
- you don't have compatible Amiga hardware with Zorro slots
- you want a plug-and-play product without FPGA toolchain involvement
