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 ...
BlueStacks introduced a new version, BlueStacks 4, in September 2018, BlueStacks 4 demonstrated benchmark results up to 6 times faster than a 2018 generation mobile phone during testing. [21] Dynamic resource management, a new dock and search user interface, an AI-powered key-mapping tool, and support for both 32-bit and 64-bit versions of ...
There are at least four main models of the 1530/C2N Datassette: The original modified Sanyo M1540A cassette drive, built into the earliest models of PET in 1977. This was a standard shoebox tape recorder with a corner of the case removed and modified electronics; a Commodore PCB was installed internally in place of the Sanyo electronics.
F2FS (Flash-Friendly File System) was added to the Linux kernel 3.8. [10] Instead of being targeted at speaking directly to raw flash devices, F2FS is designed to be used on flash-based storage devices that already include a flash translation layer, such as SD cards .
The SWTPC AC-30 Cassette Interface implements the Kansas City standard. In May 1976, it was sold for US$80 (equivalent to about $400 in 2023). The Kansas City standard ( KCS ), or Byte standard , is a data storage protocol for standard cassette tapes or other audio recording media at 300 bits per second .
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 cassette was the next step following reel-to-reel audio tape recording, although, because of the limitations of the cassette's size and speed, it initially compared poorly in quality. Unlike the 4-track stereo open-reel format, the two stereo tracks of each side lie adjacent to each other, rather than being interleaved with the tracks of ...
A D/CAS, aka "streamer" cassette, for data storage, adapted from the audio Compact Cassette format. D/CAS (Data/CASsette), also known as a streamer cassette, is a now-obsolete data backup technology that used an upgraded version of the common audio cassette tape and a specialized tape drive derived from an audio tape transport.
