USB Floppy Drive Pin Identification Chart
This page is to help you identify details about your floppy drive so that we may send the correct model.
Please look at the back of your floppy drive and count how many pins are on the larger data connector. Note where pin 1 is, it is either marked on the metal or marked on the silkscreen writing on the circuit board. The colored stripe on the ribbon cable is also an indicator, but not a perfect indicator and pin 1 may actually be on the other side.
