The open alternative, for AmigaOS, is AROS[0]. But it is not great on the original hardware. There's a crowdfunding effort to support its developers[1]. Note the significant list of already Completed projects. Otherwise, there's plenty of Open Source projects around the Amiga in github and elsewhere. Look into winuae, fsuae, amiberry and miSTer if you need emulation (via software or fpga hardware). 0. http://aros.org/ http://aros.org/ 1. https://power2people.org/ https://power2people.org/
