Back in the 80's, I wrote a letter to their documentation department asking how much certain manuals were (I was a fan). I got a box of manuals in the mail instead of a price list. They sent the references for both the 68000 and 6809. It was funny when I got to college and one of the EE courses involved programming of a 6809. Its a true shame their isn't a 64-bit 68000 as it is such a nicer processor than the x86.
