Perverted DOS idea

        There are several sources for this info. Look for Ralf Brown. He
made an "interrupt list" which is just a list of *all* interrupts.

        Mike Podanofsky wrote RxDOS, a DOS clone for the book "Dissecting
DOS" from Addison-Wellsley. His company is API Software in New Hampshire.
 for a code distribution. The documentation and comments are excellent.

That was the thing I was worried about. Maybe I'll write

Someone suggested emulation from disk, and that's exactly how I was thinking
of doing it.

Where can I find a list of INTs DOS uses? I checked a couple of bookstores
but most of them aren't too helpful with low-level DOS.
