Far ahead of its time. The 6809 was a BRILLIANT micro. It is was as clean as the 68k but in an 8-bit form. Motorola lost the plot completely when they revealed that the CPU core for the HC11 was NOT based on the 6809. Even today, the newer HC12 and HC08's are including operations that were standard in the 6809 of 20 years ago (eek!). It had great indexed and indirect addressing, very orthogonal instruction set, and pre/post increment/ decrement in 1 or 2 steps. Weep...

Oh yes, I agree with no hesitation. I cut my assembly teeth on this little beauty. IMHO, THE BEST 8-bit micro ever developed. Pity Motorola fumbled and dropped the ball. Grant Beattie wrote: > {Original Message removed}
