FPGA-based Gigatron TTL kit

Build an FPGA implementation of the Gigatron microcomputer using a Tang Nano 9K development board and a dedicated video/audio adapter board. This version implements the computer in an FPGA; the original Gigatron uses discrete TTL logic chips.

What is included

• Tang Nano 9K FPGA development board
• Adapter PCB
• Electronic components and connectors for the adapter assembly

This is an unassembled DIY parts kit. Soldering, assembly and firmware setup are required before use.

What you can build

The adapter provides resistor-network video and audio output circuitry for the FPGA Gigatron implementation, with VGA display and NES-style controller connections. This is a project for learning FPGA-based retro computing and electronics assembly.

Before ordering and building

Prepare soldering tools, a compatible VGA display and the required input device, cables and power connection for your build. If you need a particular accessory, ask us to confirm the package contents before ordering.

Use the bitstream and assembly information that match the supplied adapter revision. Contact us for the matching files before flashing firmware; an upstream project's instructions may describe different hardware.
