Open-source Intel 486 mobo built from scratch in under 6 months for i486 chips — M8SBC-486's goal was to achieve Linux and Doom compatibility, but it achieves far more than that

‘From the schematic and PCB to the chipset,’ all built from scratch. Design uses an FPGA for the chipset, bring your own i486.

          What do you mean? It is a delight to program a riscv chip (compared to the bag of legacy of x86)

        I have very mixed feelings about RISC-V since the non-profit organization moved their headquarters to Switzerland after taking a bunch of US tax dollars and grants to develop it at UC Berkeley.

          It’s an open source platform: if an american company makes and arm device, they need to pay tax to a British company. RiscV require not to pay IP tax to any foreign country.

          Also, it’s not like “they move”: stuck there in the US, they would simply shut it down. So I don’t see how your tax money went in better use.

      Good news! On the firmware side there is some serius work being done to support it!

      https://www.basicinputoutput.com/2025/01/amd-opensil.html?m=1 is AMDs work to opensource hardware intialzation

      https://opensourcefirmware.foundation/projects/ Has a good list of mostly BIOS/UEFI replacements.

      Idk about memory, Usb, sata or PCIe controllers though. (something else?)

    This looks really cool, but I have immediate concerns about the lack of ZIF socket for something designed to take 30 year old chips.
