Before anyone gets too excited about the blistering speed of the 60
MHz TMS34010, it should be noted that each TMS34010 instruction cycle
takes eight clock cycles, so the instruction cycle rate is only 7.5
MHz, and of course many instructions take multiple instruction cycles,
so the instruction rate is even lower.  However, since it has a
graphics-optimized instruction set, it was still able to do some
things noticeably faster than the 16 MHz 80186 would have.
