I still know Amiga inside out, even after all these years. I don't have to look up that $dff180 is palette entry 0. Or how to set up BPLCON and bitplane pointers, etc. in a copper list to set up a graphics mode. Alternatively you could of course do those the "proper" way through exec.library vector at address $4. But the name of the game was to extract all the performance available and that meant bypassing the operating system. :-) Programming Motorola 68000 was so simple and enjoyable. A very elegant and orthogonal design! I miss Amiga.
