An emulator of the Agon Light, Olimex Agon Light 2, and Agon Console8 8-bit computers. The Agon Light is a modern, fully open-source, 8-bit microcomputer and microcontroller in one small, low-cost board, designed by Bernado Kastrup aka The Byte Attic. As a computer, it is a standalone device that requires no host PC: it puts out its own video (VGA), audio (2 identical mono channels), accepts a PS/2 keyboard and has its own mass-storage in the form of a micro-SD card. The Olimex Agon Light 2 is a variation on the original Agon Light design. The Agon Console8 is a version of the Agon Light that also includes two Atari-compatible joystick ports, and a PS/2 mouse port, and a stylish case. It was also designed by Bernado Kastrup aka The Byte Attic, and is manufactured by Heber Ltd. The Agon Light, Olimex Agon Light 2, and the Agon Console8 are all fully compatible with each other. Software written for one will run on the other, and the same firmware can be used on both. The information about the computer is available at https://www.thebyteattic.com/p/agon.html The port provides both graphical SDL3-based emulator (fab-agon-emulator) and a terminal emulator (agon-cli-emulator).
