# Open Adaptive Amiga Retro System (Open AARS) This PCB has been designed for my project in order to run the Minimig Amiga core on a board of my own design. The core FPGA board I bought of Aliexpress, because soldering the very fine pitched BGA socket is too cumbersome. More detailed documents regarding the I/O board can be found in the docs directory in this repository. The board as is works, the features have been tested individually, but I'm still working on the Minimig port at this time. Since I work on this in my spare time progress is not super fast, but progress is made. For now I'm mostly learning and developing at the same time so a lot of stuff changes. When the code base becomes more stable and usable I'll open the repository up.  [Firmware](https://github.com/ranzbak/qmtech_minimig/blob/master/https://github.com/ranzbak/MinimigAGA_TC64) for the Amiga works! ## Interfaces provided by this I/O board - Atari/Amiga compatible Joystick ports - PS/2 keyboard interface for mouse and keyboard - Analog head phone jack via - External floppy interface to connect Amiga floppy drives (Including 12V power pin) - HDMI display connector that supports up to full HD video (1920x1080) - 6 status LEDS - Internal Amiga floppy drive connector - External Amiga floppy drive connector (DIN-23) - AS4C16M16SA-6TCN 32Mb SDRAM - ADV7511 HDMI output PHY - MAX9850 I2S Audio chip with built in amplifier - SD-card interface - RS-232 over USB to program and communicate with the Python shell ## Platforms that _could_ run with this IO board - C64 - Amiga 1200/500(+) [https://github.com/ranzbak/MinimigAGA_TC64](https://github.com/ranzbak/qmtech_minimig/blob/master/https://github.com/ranzbak/MinimigAGA_TC64) - Atari ST - Other 80's and 90's machines? Keep in mind I'm only planning on making an Amiga core for this board, but feel free to contribute other cores. # The two boards that are compatible with this design are ## QM_XC7A100T_DDR3 ### Specs - On-Board FPGA: XC7A100T-2FGG676I; - On-Board FPGA external crystal frequency: 50MHz; - XC7A100T-2FGG676I has rich block RAM resource up to 4,860Kb; - XC7A100T-2FGG676I has 101,440 logic cells; - On-Board MT25QL128 SPI Flash,16M bytes for user configuration code; - On-Board 256MB Micron DDR3，MT41K128M16JT-125:K; - On-Board 3.3V power supply for FPGA by using MP2315 wide input range DC/DC; - XC7A100T core board has two 64p, 2.54mm pitch headers for extending user IOs.
