Item and Condition Notes
Power on tested, as pictured, no top cover on this unit. You have a TEAC FD-505 302-U, a dual-format internal floppy disk drive designed for IBM PC-compatible computers.
What makes this device interesting is that it combines two independent floppy disk mechanisms in a single 5.25-inch drive bay. It was an elegant solution during the transition from 5.25-inch floppy disks to 3.5-inch disks in the early 1990s.

Serial number 2213318
Origin Malaysia
Form factor 5.25-inch, half-height bay

34-contact edge connector. This is a traditional floppy disk interface, not IDE, SATA, or SCSI.
– Data: 34-pin floppy interface.
– Power: Conventional 4-pin peripheral power connector, supplying 5V and 12V.
– Drive selection: Configurable so the 3.5-inch and 5.25-inch mechanisms can operate as separate A: and B: drives.
– Modern computers: Typically require a compatible legacy floppy controller or specialized preservation hardware. Ordinary USB floppy adapters generally won’t support both mechanisms.
– Both eject buttons and the front bezel are present.
– The main spindle motor and controller boards are visible.
– No obvious severe corrosion or burned components are apparent.
– The two mechanisms cannot be confirmed functional from photographs.
– The exposed configuration does not by itself establish whether the drive belts, heads, or mechanical assemblies need maintenance.
Power Adapter: Does Not Apply — this device does not require a power adapter or detachable power cord.
