This made me look up if you could somehow run it on vacuum tubes, sadly not

    OMG!

    I booted Debian Linux on a 4-bit intel microprocessor from 1971 - the first microprocessor in the world - the 4004. It is not fast, but it is a real Linux kernel with a Debian rootfs on a real board whose only CPU is a real intel 4004 from the 1970s. The video is sped up at variable rates to demonstrate this without boring you. The clock and calendar in the video are accurate. A constant-rate video is linked below.

    Of course you can run it on tubes, in principal, since they do the same as transistors at the end of the day
