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]
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 ...
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.
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 ...
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 ...
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 ...
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.
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.
