Bean, 

I've been trying to figure out some things with your code.  Using the original example, it appears that your maximum horizontal resolution is 80 pixels.
You hold those values in $B0 - $FF.  Correct?

Next, in your active scanline, it appears that you first grab the current register (starting with $B0), then you RL 7 times.  You do this for exactly 40 clocks (2 CBC's).  I can't quite figure out what the RL's are for.  In other words, why are you shifting the register values?

Thanks!
