Discussion of the DIY-A586 v1.9 FPGA-based Amiga-compatible board by piotr_go, built around a Spartan-6 XC6SLX9 with 32 MB SDRAM, 16 MB flash, HDMI, analog audio, SD, RS232, joystick, PS/2, floppy and A500 keyboard interfaces. The thread covers core architecture (own core with TG68 CPU), compatibility, FPGA resource usage, synthesis constraints, and comparisons with Minimig/MiSTer. A large part of the discussion focuses on assembly and bring-up: flash programming, ROM loading, SD card formatting, Kickstart patches, floppy-drive conversion, Gotek compatibility, SDRAM timing, oscillator choice, and soldering order. Later posts report fixes and updates for Amiga core, SD support, PS/2 reset, floppy reading, audio, and bitplane handling, plus questions about parts sourcing, connector footprints, and possible future ports or expansions such as AGA, C64, Spectrum, and alternative FPGA platforms.
