M8SBC-486 is a homemade 486 computer motherboard, built from scratch, aimed at running Linux and DOOM. It’s “kinda PC compatible” with some limitations (e.g., missing DMA impacts sound support). Features include a 4-layer PCB, 5V 486 CPU socket, and support for certain ISA cards and DOS operating systems. The project is experimental and a hobby, reflecting extensive research on older x86 chips. Supported by PCBWay, the project has various compatibility notes for hardware and software. More details can be found on multiple dedicated subpages.
