IBM 3740

IBM 3740 Data Entry System was a data entry system that was announced by IBM in 1973. It recorded data on an 8" diskette, a new recording medium from IBM, for fast, flexible, efficient data entry to either high-production, centralized operations or to decentralized, remote operations. The "Diskette" was more commonly known as an 8-inch floppy disk.
