About the Videoslotadapter PCB

Videoslotadapter is an open source PCB design by hoglet67, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 152 × 57.6 mm, with 13 components from 10 distinct parts.

Other key parts include the XC9572XL-VQFP44, 74LVC574 and TLV74333PDBVR. By type, the board carries 4 ICs, 4 capacitors, 1 jumper and 1 resistor.

It belongs with the retro computing designs in this gallery.

From the project

Bare-metal Raspberry Pi project that provides pixel-perfect sampling of Retro Computer RGB/YUV video and conversion to HDMI

This adapter builds on the ideas from the Amiga Denise adapter V2, adapted for use in big box Amiga video slots.

The main differences are: - The 7MHZ signal is derived via C1 XNOR C3 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.
