I had a 6809 card like this from a company in the southwest US. It came 
with a p-code interpreter and assembler written in 6809 assembly. At the 
same clock speed it was 5-20% faster than the 6502. It sped up Apple's 
UCSD p-System et al. enough to make it appealing. I still have the A/O 
6809 assembly language book by lance Leventhal.
