A 'universal' cable would have four drive connectors, two for each size of FDD, although cables which have only two drive connectors are common. The cable is normally a ribbon cable. For IBM-compatible floppy controllers, a twist in the cable reverses the order of conductors 10 through 16 for the second connector.
Many types of Berg connectors exist. Some of the more familiar ones used in IBM PC compatibles are: the four-pin polarized Berg connectors used to connect 3½-inch floppy disk drive units to the power supply unit, usually referred to as simply a "floppy power connector", but often also referred to as LP4. This connector has a 2.50 mm (0.098 in ...
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.
The early Macintosh and late Apple II computers used a non-standard 19-pin D-sub for connecting external floppy disk drives. Atari also used this connector on their 16-bit computer range for attaching hard disk drives and the Atari laser printer, where it was known as both the ACSI (Atari Computer System Interface) port and the DMA bus port.
The desktop computer hard-drive connector (AMP Mate-n-Lok 1-480424-0 power connector) is standard on all 5.25-inch floppy drives, 3.5-inch PATA and non-SCA SCSI disk drives; however, newer SATA disk drives employ a more advanced interconnection with 15 contacts. These advanced connection systems were first developed by Molex and other connector ...
Part of a Mk3 (red/black audio cables) The Catweasel is a family of enhanced floppy-disk controllers from German company Individual Computers.These controllers are designed to allow more recent computers, such as PCs, to access a wide variety of older or non-native disk formats using standard floppy drives.
The printed circuit board was sized to match the Shugart 801 or 851 floppy drive. This allowed attachment to up to two 8 inch or 5 1/4 inch floppy disk drives. The Big Board II added a SASI interface for hard disk drives, enhancements to system speed (4 MHz vs. 2.5 MHz) and enhancements to the terminal interface. [2]
The Timex FDD 3000 is an upgraded Timex FDD (sometimes known as the FDD3 because it consisted of three separate boxes: a floppy-disk drive, the controller and the power supply). [ 3 ] [ 1 ] [ 2 ] The Timex FDD3 was intended as a floppy disk peripheral for the Timex TC 2048 or TC 2068 microcomputers . [ 3 ]
