I would depend on the kind of instructions used, but I beleive that the 68k
would be faster for almost anything. My guess is that a 68k @ 10 MHz is app
twice as fast as a 6 MHz Z80, but I am just guessing. I have been using the
TI92 since it was released, and there is no doubt that the processor is
faster than a 6 MHz Z80.
