Despite my own
assumption about the roller being the problem, I
shouldn't have said one would think it could be done self-clocking
without a roller - I know it can be done self-clocking without a roller:
I looked back at my docs for the reader project and see I picked the
data & clk outputs off the read amps and interpreted them with an
assembly program - no roller sensing involved.
Just a PLL...doing self-clocking in that manner is pretty easy.
