No you didn't. You can't even write a bootloader without 3. All practical computers have always had 3.

- ncmncm 6y agoYou reveal that you have never programmed a microcontroller. Most do not have an OS, and cannot run the compiler used to program them. Yet, they are practical: the world would grind to a stop if they vanished. Most today are far more powerful than any among the whole first decade of practical computers. Those ran compilers in as little as 4k words of memory. The output of the compiler was not written to memory; it was punched directly to tape or cards. (On some, it physically could not be written to program memory, even if there were room: no bus connected to there.) The tape was later read into program memory--often onto a spinning magnetic drum--and executed directly, no OS in sight. If you imagine these were not practical computers, consider that people paid $millions for them; they earned their keep. Have you ever operated a computer doing work worth that much?
