    Not quite just a transistor but maybe something like this (an SOC with 32MB ram which costs about $5 in bulk) though it does require quite a bit of additional electronics to work.

    Also somebody also made an embedded Linux for the ESP32-S3 (which is even cheaper and doesn’t require anywhere as much auxiliary electronics).

    PS: Yeah, I got the joke. Just pointing out that the reality itself is quite impressive.

      I’m sure someone could figure out how to boot Linux on a vacuum tube computer. The problem is there just aren’t that many around that are still operational.

      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

    The 2N3904 isn’t “minimum requirements for Linux” - it’s one bipolar transistor, and a Linux-capable computer still needs a CPU made from vastly more transistors, plus RAM, storage, clocking, buses, and supporting hardware. Not funny.

          GNU/Linux Copypasta

          I’d just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

          Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.

          There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!

      Plot twist: it’s actually a whole SoC packaged to look like a single transistor, with the pins being for +V, ground, and a 1-Wire data bus.

      I don’t know that such a thing exists, but these days I bet it could.

      You’re right. A lightbulb plugged into a potato is the real minimum system requirement.

      Linux requires at least 32 bit machine words, and it always has. Linux was originally written for Intel 80386.

      Linux requires a hardware MMU to support virtual memory. There are patches that can make a no-MMU kernel, but it drastically changes the experience to do so.

        Well it is kinda cheating but Linux does “run” on a intel 4004 running a MIPS emulator

        I think you could cook something like a 4-bit turing complete computer with around 100 transistors or so. And i guess turing completeness basically means “it will run with enough elbow grease” in this case

        (if we exclude memory from the transistor count…)
