Custom uber simple OS? Answered

After playing in the world of arduino for a while I have become curious if it is possible to use a common cpu, motherboard ect. To do the same thing as with a small microprocessor. Could one for example load the arduino bootloader to a cpu or just write to it with serial in order to use it for purposes similar to arduino and picaxe.  I know its a weird and wasteful idea but im just curious if it is even possible with modern electronics. I dont think it would be hard to find a junked old desktop and even if it was 1 mhz (much more likely to be 1 ghz) it would be extremely fast. Could you imagine an arduino with that clock speed! You could measure the length of pulses much smaller and you would be able to potentially handle 32 bit and maybe even 64 bit operations. Just a curious thought I had, could it be done and what would you do with such a system

The idea was to do something cool with an old cpu, which one is already in possession of. I know the alternatives quite well, but I was curious if one could get the same bare-bones computing out of an old cpu, and I now believe that answer is no.

The arduino bootloader will not work with a CPU. It is designed to work only with a certain range of micro controllers. It's only able to handle 8 bits. If you want the power of a small PC and the ease of use of a micro controller then get a Raspberry Pi or Beagle bone board and start learning Linux. It is a much more powerful, useful and lucrative system to know and understand. Otherwise get an older PC and a copy of DOS 6.0 and learn to program in basic.

You can also do supprising things with a spread sheet if you know how.

If you use a pic stamp programming in Pbasic which compiles to tokens.

When you are satisfied with the software operation you can convert the compiled token to straight machine code.

Which can be immediately applied to a $3 microchip and used in place of the stamp.
