You write about this experiment with considerable
confidence in your result,
considering that you haven't any conventional hardware for dealing with this
stuff. There must be something about your results that gives you the
confidence to proceed. What might that be? Are you getting verifiable
results, i.e. data that makes sense like ascii files, etc?
Yes, ASCII (and EBCDIC, remember I'm recovering floppies originally written
in the early 70's) files that make sense.
I think, Dick, that sometimes you make this seem harder than it is. Many
of the data formats are readable (in hardware) with something as simple as
a one-shot and a UART.
Sampling and recording the analog signal might prove
disappointing. The
data will be much harder to recognize in its analog form, particularly on
the inner tracks on a noisy diskette or drive.
True, but the analog circuit would also be easy to simulate electronically.
Just a few coupled linear and nonlinear differential equations!
