Prior to the introduction of the Disk II, cassette was the main storage medium for Apple machines. Here an Apple II is using a Panasonic tape deck. The Apple I introduced an expansion-card based cassette system similar to KCS, recording a single cycle of 2000 Hz for a space and a single cycle of 1000 Hz for a mark. This resulted in an average ...
The Datasette has only one connection cable, with a 0.156-inch (4.0 mm)–spacing [6] PCB edge connector at the computer end. All input/output signals to the Datasette are all digital, and so all digital-to-analog conversion , and vice versa, is handled within the unit.

The Quick Emulator (QEMU) [4] is a free and open-source emulator that uses dynamic binary translation to emulate a computer's processor; that is, it translates the emulated binary codes to an equivalent binary format which is executed by the machine.
Magnetic tape was first used to record computer data in 1951 on the UNIVAC I. [8] The UNISERVO drive recording medium was a thin metal strip of 0.5-inch (12.7 mm) wide nickel-plated phosphor bronze. Recording density was 128 characters per inch (198 micrometres per character) on eight tracks at a linear speed of 100 in/s (2.54 m/s), yielding a ...
The 8-track tape (formally Stereo 8; commonly called eight-track cartridge, eight-track tape, and eight-track) is a magnetic-tape sound recording technology that was popular [2] from the mid-1960s until the early 1980s, when the compact cassette, which pre-dated the 8-track system, surpassed it in popularity for pre-recorded music.
