`::The 68k is not just a bootstrapping device. In fact, the term ``bootstrapping`` implies that this is the ``Central`` Processing Unit (CPU) and nothing else. It is no more ``bootstrapping`` than any other computer system with additional dedicated graphics and sound processors. The GPU has several severe bugs so that almost no games use it for anything but graphic routines and the 68k runs all the game logic. Especially because the DRAM is shared across all processors, it was (in theory) possible to use the GPU for some typical CPU routines which is the purpose of accelerator devices like these. However, the 68k is clearly the central unit. It doesn't matter how much of the work it does and the other processors are obviously not labeled as ``CPU``. The term ``object processor`` seems to be an Atari invention anyway and I doubt it has anything to do with OOP as the wiki-link implies.     `
