The de facto standard 5.25 inch FDD interface is based upon the Shugart Associates SA400 [6] FDD. [5]: 169 The signal interface uses a 34-pin PCB edge connector which mates to a flat ribbon cable connector. DC power is provided on a separate connector. [6] The 34-pin connector is similar in pinout to the standard 50-pin connector for 8 inch FDDs.
Parallel ATA (PATA), originally AT Attachment, also known as Integrated Drive Electronics (IDE), is a standard interface designed for IBM PC-compatible computers.It was first developed by Western Digital and Compaq in 1986 for compatible hard drives and CD or DVD drives.
8-pin (left) and 6-pin (right) power connectors used on PCI Express cards. Optional connectors add 75 W (6-pin) or 150 W (8-pin) of +12 V power for up to 300 W total (2 × 75 W + 1 × 150 W). Sense0 pin is connected to ground by the cable or power supply, or float on board if cable is not connected.
A standard-sized 8-pin dual in-line package (DIP) containing a 555 IC.. Integrated circuits and certain other electronic components are put into protective packages to allow easy handling and assembly onto printed circuit boards and to protect the devices from damage.
SASI, which was used in mini- and early microcomputers, defined the interface as using a 50-pin flat ribbon connector which was adopted as the SCSI-1 connector. SASI is a fully compliant subset of SCSI-1 so that many, if not all, of the then-existing SASI controllers were SCSI-1 compatible.
The standard floppy drive was upgraded to a 1.2 MB 5 + 1 ⁄ 4 inch floppy disk drive (15 sectors of 512 bytes, 80 tracks, two sides), which stored over three times as much data as the 360 KB PC floppy disk, but had compatibility problems with 360k disks (see Problems below).
