I should have gone back and looked through my code and comments a little better last night before posting.  I was just at that point where I was getting really frustrated and really tired.  I was going to wait before posting but I figured it would mean at least another day before getting any help.

Glen,
You are still sending the wrong value to $FF91. You do NOT! want to set the 
timer select TINS to the fast rate.
By the way, the service manual claims 1 = 70nsec but I've timed it and it is 
related to the color burst not the master clock; so more like 279nsec.

I'll be testing the latest code snippets but it would be much easier to 
proofread your code if you sent me the full source.
