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 ...
KryoFlux reads "flux transitions" from floppy disks at a very fine resolution. [6] It can also read disks originally written with different bit cell widths and drive speeds, with a normal fixed-speed drive. [7] The software is available for Microsoft Windows, [8] Mac OS and Linux. The KryoFlux controller plugs into a standard USB port, and ...
The floppy disk emulator can provide other systems access to the data on the emulated floppy in a number of ways: Direct access to some dedicated disk partition (e.g.: a 1.44MB partition on a USB key) Floppy file system translation (e.g.: FAT12 floppy ↔ USB key folder) Floppy disk images (e.g.: raw floppy ↔ .img/.iso USB key file)
A similar file extension, .ima, is also used to refer to floppy disk image files by some programs. A variant of IMG, called IMZ, consists of a gzipped version of a raw floppy disk image. These files use the .imz file extension, and are commonly found in compressed images of floppy disks created by WinImage.
The Mac OS Calculator as it shipped in 1984, with System 1 Apple's iOS calculator app adjacent to a Braun ET 66 electronic calculator. The Calculator program has a long associated history with the beginning of the Macintosh platform, where a simple four-function calculator program was a standard desk accessory from the earliest system versions.
System 7.0 and 7.1 have a utility called Apple File Exchange, which accesses the contents of FAT- and Apple II-formatted floppy disks. Since System 7 Pro, PC Exchange is included, which allows the system to mount FAT-formatted floppy disks on the desktop like Macintosh disks. OS/2 disks can use the FAT file system. Macs can read and write UNIX ...
The disk format uses group coded recording (GCR) in a manner very similar to that of the Disk II. The drive contains circuitry to allow software control over the motor speed, which is used to maintain near constant flux transition rate on all tracks, so that more data can be stored on the outer tracks.
An Apple Macintosh computer running Disk Copy 6.3.3 on the Mac OS 7.6 or later operating system can copy and make DMF disks. [3] The first Microsoft software product that uses DMF for distribution were the "c" revisions of Office 4.x. It also was the first software product to use CAB files, then called "Diamond". Comparison of DMF and standard ...
