6 * different m68k hosts compiled into the kernel.
7 * Currently the Atari has 72 and the Amiga 24, but if both are
8 * supported in the kernel it is better to make room for 72.

31 * Interrupt source definitions
32 * General interrupt sources are the level 1-7.
33 * Adding an interrupt service routine for one of these sources
34 * results in the addition of that routine to a chain of routines.
35 * Each one is called in succession. Each individual interrupt
36 * service routine should determine if the device associated with
37 * that routine requires service.
