Description

This project implements a board which plugs into a big-box Amiga Video Slot (A2000, A3000, A4000) and uses a Raspberry Pi Zero to process the Amiga display video in realtime to provide HDMI video output for the computer.

The Amiga Video to Pi HDMI is a card designed for the "big box" Amiga video slot. Using a Raspberry Pi Zero, it can convert and output HDMI video from the Amiga native video formats (only OCS modes are supported).

The schematic design is based loosely on LinuxJedi's CPLD version of the Denise socket Amiga-Digital-Video module for OCS and ECS Amigas with a 48-pin DIP Denise.     https://github.com/LinuxJedi/AmigaRGBtoHDMI/tree/main/Amiga500CPLD     https://github.com/c0pperdragon/Amiga-Digital-Video

It uses software for the Raspberry Pi Zero that is developed by hoglet67's multi-platform vintage hardware RGBtoHDMI project:     https://github.com/hoglet67/RGBtoHDMI
