> The differences between the 6809 and modern architectures makes for some interesting learning! Funnily enough, the 6809 is by far the most "modern" 8-bit design. It was the last major one, released after the Intel 8086 and some other 16 bit designs. Stack-relative addressing (with two stacks!), position-independent code, 16 bit arithmetic, hardware multiplication, and high code density. Very nice compared with the likes of the Z80 or 6502.
