3.5-inch floppy disk drive interface (adaptable to other sizes) KryoFlux is a hardware and software solution for preserving software on floppy disks . [ 2 ] [ 3 ] It was developed by the Software Preservation Society.
It supported all of Apple's 3.5" floppy disk formats as well as all standard PC formats (e.g. MS-DOS, Windows), allowing the Macintosh to read and write all industry-standard floppy disk formats. The external drive was offered only briefly with support for the Apple II, coming late in that product's life.
3.5-inch and 5.25-inch drives connect to the floppy controller using a 34-conductor flat ribbon cable for signal and control. Most controllers support two floppy drives, although the Shugart standard supports up to four drives attached to a single controller. A cable could have 5.25-inch style connectors, 3.5-inch style connectors, or a ...
Internal SuperDrive floppy drive on a Macintosh LC II. The term was first used by Apple Computer in 1988 to refer to their 1.44 MB 3.5 inch floppy drive.This replaced the older 800 KB floppy drive that had been standard in the Macintosh up to then, but remained compatible [citation needed] in that it could continue to read and write both 800 KB (double-sided) and 400 KB (single-sided) floppy ...
Circuit components of the external USB SuperDisk for Macintosh. The drive itself is the same size as a standard 3.5″ floppy drive, but uses an ATA interface. On the right is the USB-to-ATA adapter, which plugs into an intermediate fan-out and power supply daughterboard that is inside the rear of the Mac drive's casing.
With Apple Computer's release of the Apple IIGS, Applied Engineering followed with a TransWarp GS, which provided an accelerated version of the 65C816 processor on which the IIGS was based. Multi-function cards were a mainstay of AE's product offerings, of which the Serial Pro serial interface card was a typical example.
The host Macintosh requires special emulation software (a boot disk) launched from System 6.0.8 to 7.5.5 in order to activate the IIe Card. Apple II mode runs only in full-screen (a windowed mode is not possible) and all Macintosh operations are suspended while running, as the IIe card takes over the host computer.
When the controller and disk drive are assembled as one device, as it is the case with some external floppy disk drives, e.g., Commodore 1540 and USB floppy disk drives, [27] the internal floppy disk drive and its interface are unchanged, while the assembled device presents a different interface such as IEEE-488, parallel port or USB.
