A2FPGA
The A2FPGA is primarily an HDMI video and sound for the Apple II, II+, //e, and IIgs. It's an Apple II peripheral card that can be installed in any Apple II slot (slot-7 recommended except for the IIgs which requires slot 3) that uses a modern FPGA (field-programmable gate array or "programmable logic") to provide precise timing-accurate interfacing to the Apple II bus. This allows the card to capture all access to Apple II display memory in order to faithfully generate Apple text and graphics in crisp 480p HDMI as well as providing the functionality of a number of popular peripheral cards in a single Apple II slot. The A2FPGA has been tested with Apple II, II+, //e, and IIgs models and brings the classic Apple II experience to any monitor or television.
The A2FPGA firmware is easily updated on any PC or Mac and is based on open-source code so that new functionality and bug fixes from the developer community can be added over time. You can learn more about this exciting project on its public GitHub repository: https://github.com/a2fpga/a2fpga_core.
