Well, I figured out part of my problem with the keyboard controllers.
I was using a borrowed piece of code to do the VBlank part of my program
and it still was writing a 1 to D7 of VBlank.  This was dumping Inpt0,
Inpt1, Inpt2, Inpt3 to ground and thus I couldn't read them properly.
Now I fixed that one value in my program and now I am getting a reaction
from columns 1 and 2 on the keyboard controller.

So the moral is: when using the keyboard controllers, don't forget that
Inpt0 through Inpt3 are not the same as Inpt4 through Inpt5 and thus
if you aren't careful you can't read columns 1 and 2 on the controllers.

Back into the fray...
