"A troll might say, "It can crash!" We used DOS for years and loved it. Computers even had a reset switch! ... Think of the speed and simplicity of ring-0-only and identity-mapping. It can change tasks in half a microsecond because it doesn't mess with page tables or privilege levels. Inter-process communication is effortless because every task can access every other task's memory."I'm not a troll, but being old enough to have programmed on operating systems where a bad pointer reference could force you to reboot the machine (DOS, early versions of Windows, early versions of MacOS), I don't yearn for those days to come back. DOS was designed the way it was to allow it to run on cheap (for its time) hardware, not because anyone thought that it was a good development environment (Unix already existed at the time, so people knew how to write a robust operating system).
Also, is it a good idea to connect a machine that has an unprotected operating system to the internet?
Clearly this software reflects a lot of effort and ingenuity, but I doubt that people could be convinced to pay money for it.
