Description
Amiga A2000 Video Slot RGB to HDMI
Amiga Video Slot Adapter
This Amiga-Digital-Video project designed by Bloodmoshert, builds on c0pperdragon's Amiga-Digital-Video project, adapted for use in big box Amiga video slots.
The main differences are:
- The 7MHZ signal is derived via C1 XNOR C3 using an additional 74LVC86 since 7MHZ is not available directly from the video slot
- Two button connectors allow for both a rear slot cover bracket button and another to be used, mounted wherever desired
The card edge connector used is from Amiga-KiCad-Library (https://github.com/JustinBaldock/Amiga-KiCad-Library). Approximately 1mm of space is left between the fingers and the PCB edge to allow for beveling.
Installation notes:
- Set the Denise jumper according to which Denise is in your Amiga (Super Denise for 8373, Denise for 8362)
- Orient the PCB such that the end with bracket mounting holes faces the rear of the machine.
Software:
- A compatible release of the software is available from the RGBtoHDMI repositoryhttps://github.com/hoglet67/RGBtoHDMI/releases.
- Unzip the content of the archive to the root folder of a micro SD card, formatted as FAT32, and put in your Raspberry Pi Zero.
