The cost may be comparable. That's true only if you're not multitasking. In a multitasking OS the CPU might get a lot of use, even if it is faster. The blitter will assure that the CPU will not be interrupted for various simple but necessary tasks (such a windowing, sizing, menu operations, etc...). Of course, if you get a Mac II just to run Mac software than the 68020 is fast enough such that you won't need a blitter. But, a blitter will be necessary when running multiple Mac applications under A/UX (if such a thing will ever be possible). Ali
