  2. KryoFlux - Wikipedia

    en.wikipedia.org/wiki/KryoFlux

    KryoFlux consists of a small hardware device, [4] [5] which is a software-programmable FDC system that runs on small ARM-based devices that connects to a floppy disk drive and a host PC over USB, and software for accessing the device. KryoFlux reads "flux transitions" from floppy disks at a very fine resolution. [6]

  3. Bit nibbler - Wikipedia

    en.wikipedia.org/wiki/Bit_nibbler

    A bit nibbler, or nibbler, is a computer software program designed to copy data from a floppy disk one bit at a time. It functions at a very low level directly interacting with the disk drive hardware to override a copy protection scheme that the floppy disk's data may be stored in. In most cases the nibbler software still analyses the data on ...

  4. Self-booting disk - Wikipedia

    en.wikipedia.org/wiki/Self-booting_disk

    On other systems, like the Apple II and Atari 8-bit computers, almost all software is self-booting. On the IBM PC, the distinction is between a self-booting program and one which is started by the user via an operating system such as MS-DOS or IBM PC DOS. The term "PC booter" was not contemporaneous with when self-booting games were being released.

  5. SpinRite - Wikipedia

    en.wikipedia.org/wiki/SpinRite

    SpinRite is claimed by its developer to have certain unique features, [4] such as disabling of disk write caching, disabling of auto-relocation, compatibility with disk compression, identification of the "data-to-flux-reversal encoder-decoder" used in a drive, and separate testing of buffered and unbuffered disk read performance, and direct ...

  6. Commodore 1581 - Wikipedia

    en.wikipedia.org/wiki/Commodore_1581

    An internal floppy drive and controller are required as well; USB floppy drives operate strictly at the file system level and do not allow low-level disk access. [9] The WD1770 controller chip, however, was the seat of some early problems with 1581 drives when the first production runs were recalled due to a high failure rate; the problem was ...

  7. Commodore 1571 - Wikipedia

    en.wikipedia.org/wiki/Commodore_1571

    The Commodore 1571 is Commodore's high-end 5¼" floppy disk drive, announced in the summer of 1985. With its double-sided drive mechanism, it has the ability to use double-sided, double-density (DS/DD) floppy disks, storing a total of 360 kB per floppy. It also implemented a "burst mode" that improved transfer speeds, helping address the very ...

  8. Fast loader - Wikipedia

    en.wikipedia.org/wiki/Fast_loader

    A emulator screenshot of a program being loaded from disk using a fast loader. A fast loader is a software program for a home computer, such as the Commodore 64 or ZX Spectrum, that accelerates the speed of file loading from floppy disk or compact cassette.

  9. Advanced Disc Filing System - Wikipedia

    en.wikipedia.org/wiki/Advanced_Disc_Filing_System

    The Advanced Disc Filing System (ADFS) is a computing file system unique to the Acorn computer range and RISC OS-based successors.Initially based on the rare Acorn Winchester Filing System, it was renamed to the Advanced Disc Filing System when support for floppy discs was added (using a WD1770 floppy disc controller) and on later 32-bit systems a variant of a PC-style floppy controller.
