I'm a bit surprised that there don't seem to be any adaptations that
hook into the head pre-amps and use an ADC to give a view of what the
read signal actually looks like. Maybe that's asking too much--there
are certainly MCUs with sufficiently fast ADCs and memory to do this.

Many companies make suitable vehicles, but NONE of them are willing to call
them "station wagons". If the Purchase Order explicitly specifies "Station
Wagon", then will the bureaucrats in purchasing let you substitute a
"Variant", instead of a "Station Wagon"?
