※ This is from when I was playing on NEC PC-98s. I cannot guarantee its usability, but please consider it as a reference. This is a set of MS-DOS 6.2 basic functions for the NEC PC-9800 series, consisting of 8 floppy disks. Operation has not been confirmed. Please consider it as junk. Please research the compatible computers yourself. Also, it is very old. There is a possibility that it cannot be read. Please consider purchasing with the understanding of this. Please refrain from price negotiations. Thank you.
