This vintage computer accessory was designed to cut a second write-enable notch in compatible 5.25-inch floppy diskettes, allowing the reverse side to be used for additional storage. The original packaging lists compatibility with Apple II, Atari, Commodore, Franklin, Kaypro, and compatible computers.

Condition: Pre-owned vintage condition. The blue disk coupler is in good physical condition for its age and the mechanism moves. There is handwritten marking on the housing as shown. Original box is included but has significant age/storage wear, including creasing, tears, edge wear, and damaged flaps. Please review all photos carefully for exact cosmetic condition.

Original packaging states Made in Taiwan, R.O.C.
