I don't have the technical information to answer the question of
interrupt vectors  with specifics. But, I do know that the ST can change
the color registers scan line by scan line just as the Amiga and old
Atari 800 could. This is usually done with "periodic interrupts".

I am trying to program the ST in Hippo C with grossly inadequate
documentation about the machine. Can anyone tell me how to read the
joystick ports. Also, if any one knows, how do you use the BitBlt
capabilities.
