Hey #6809 nerds! What's the fastest "multiply an 8-bit number by 10 into a 16-bit number" routine you can come up with? I just wrote up one that is tailored to this that plays with A being the msb of D that's 47 cycles. Barrow's book has a 16-bit x 8-bit that uses 2 MULs ... might be faster, but I need to count the cycles. Whatcha got, wizards? #retrocomputing
