A hobbyist built a 486-style motherboard using an FPGA and pure determination
SMRTR summary
Hobbyist programmer Piotr Grzesik successfully created the M8SBC-486, a homebrew 486-style motherboard using an FPGA-based custom chipset that mimics vintage PC hardware without requiring an actual Intel 486 processor. The experimental board features 4MB of SRAM and two ISA slots, successfully running MS-DOS, FreeDOS, and classic games like Doom and Prince of Persia, though it lacks full compatibility with Windows systems and sound cards due to missing components like DMA support.
