Oldenbourg Verlag, ISBN 3-486-22892-7. I have the 2nd edition. I've found them on many university librarys. > Confess I've never read the details of the 6809. Point > taken though. The 6809 is a very different chip. Although it is an 8 bit processor, it has some commands which use two registers as 16 bit ones (comparable with the way the 8080 does). I've worked with that one many years ago and I found it very interesting. I even once had a plan to put an 6809 on the C64's expansion port, but never got that far so I had a complete schematic which even would be complete - I don't speak of being able to work! Spiro.
