I remember my first Mac lacked a math coprocessor. It was the Motorola LC68040, and it came with Quadra 604. I seem to remember it making Excel slow at doing so

I remember my first Mac lacked a math coprocessor. It was the Motorola LC68040, and it came with Quadra 604. I seem to remember it making Excel slow at doing some calculations. My next Mac was a PowerPC, I don't remember any of those lacking math coprocessors.
