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.
