For sale is an external 3.5-inch floppy disk drive (PC-9801 NL/R-02) compatible with NEC PC-9821 Lt and other models. As shown in the second photo, it was connected to my PC-9821Lt and used to run a demonstration program (the computer and floppy disks are not included in the sale). I have also confirmed that it works with 1.44MB, 1.2MB, and 640KB floppy disks. This floppy disk unit appears to be compatible with PC-9821 Ld, PC-9801NL/R, and PC-9801 NL/A, but I haven't been able to confirm this as I don't have those computers. How about this working floppy disk drive, which has become a rare item these days?
