[Coco] Optimizing 6809 Assembly Code: Part 2 – Speedup Storing Data – Unrolling Loops

[Mark McDougall]

Hi Glen,

Great series of articles!

Wasn't aware of the tfr/leau optimsiation - although I did note that tfr 
was _slow_! Just went through Knight Lore (some news on that subject 
very soon) and replaced 14 occurrences - thanks!

It also reminded me to look for bsr,rts and I found a few of those as 
well but in my defence, I was focused at the time on keeping the code 
"the same" as the original! ;)

Regards,
