The 6809 was a relative bit player; nifty chip but too late in the 8-bit market cycle to get nearly the traction or ship remotely the numbers its competitors did. By the time it hit the market, if needed the uptick in performance/features, you usually went to one of the 16-bit chips. If you're including 'derivatives', then the 68hc11 and related (6800 with extra stuff) were/are wildly popular in the embedded space and are still today being produced by NXP. You can buy them from stock at Digikey. The 6809 never superseded the 6800 at anything in the market other than being cool. And then the 68000 ate whatever market it might have had left. Agreed on the 8051. There's probably a dozen within 20' of you right now.
