Yup. I've still got one of the FlashPath units after having taken one
apart and destroyed it in the process.
There;s a small electromagnet (coil) located where it can be coupled to
the drive head. The rest is pretty straightforward--an Atmel MCU, some
RAM and random logic, along with the driver/sense to the electromagnet.
There's no way for it to determine what cylinder the floppy drive is
positioned to, nor any way for it to determine when the Index position
is being passed, which is why it requires a driver on the host to operate.
Aha! Interesting. So it's not actually able to be read as if it were a
diskette? It's sort of hijacking the drive as an alternative I/O
medium, pulsing data at a stationary drive head, ignoring rotation and
track positioning?
