The 26P of this adapter card is a 1.0MM pitch drawer-type top connection, and the 34P is a 2.54MM pitch female socket. This card can be used to convert the 26P 1.0MM interface floppy drive to a 34P ordinary 1.44MB floppy drive or simulated floppy drive. It can be used normally after testing. Easy data transfer between your computer and floppy System:support winxp, winme, win7 32bit, win7 64bit, win10 Please Note: this cable will NOT improve the read/write speed of floppy For 1.44mb Floppy Only.Reliable and efficient When wiring, connect according to the line sequence markings of each interface. If the connection is wrong, it will not be used. If the 1# of the 1.0MM FFC/FPC 26P soft cable of the device/computer does not match the 1# of the adapter card, it means that the 26P soft cable is wrong and needs to be replaced. There are two types: the same direction cable and the reverse direction cable. Regarding whether the soft cable matches, you can compare it with the 26P interface in the picture. The actual picture is a 1.0 MM 26P drawer-type top connection. The silk screen on the board is different due to different batches Colour:Green Material:PCB+Plastic Package Contents: 2 x 26P to 34P Converter 2 x cable
