Nice article, fun reading; brings back many memories. That was the first processor we used for our exercises at ETH Zurich in the eighties. I remember well that there was actually no real introduction and we students were just supposed to know how to program the 6809 on assembler level from one day to the other. At that moment, the students were split into two camps; some of them bought and devoured books about the 6809 to make up for the lack of lectures; others threw computer engineering to the wind and tried their luck with traditional electrical engineering; fortunately, I made it to the former. Shortly afterwards, I started building digital musical instruments.
