An IEEE 1284 36-pin male micro ribbon printer cable connection. The computer side normally uses a DB-25 port instead of this connector. IEEE 1284, also known as the Centronics port, is a standard that defines bi-directional parallel communications between computers and other devices.
This size, with 36 pins and bail locks, is also known as a Centronics connector because of its introduction by Centronics for use with the parallel port of printers, and is standardized as IEEE 1284 type B. Other connectors of this size are also called Centronics connectors. The smaller size has 0.050 inch (1.27 mm) pitch. This size, with 36 ...
When IBM implemented the parallel interface on the IBM PC, they used the DB-25F connector at the PC-end of the interface, creating the now familiar parallel cable with a DB25M at one end and a 36-pin micro ribbon connector at the other. In theory, the Centronics port could transfer data as rapidly as 75,000 characters per second.

A spacing of 0.05 inch (1.27 mm) is the most usual, allowing for a two-row connector with a pin spacing of 0.1 inch (2.54 mm). These types are used for many types of equipment, in particular for interconnections within an enclosure. For personal computers, this size was used in floppy-disk-drive cables and older or custom Parallel ATA cables.
The original Zip drive has a maximum data transfer rate of about 1.4 MB/s (comparable to 8× CD-R; although some connection methods are slower, down to approximately 50 kB/s for maximum-compatibility parallel "nibble" mode) and a seek time of 28 ms on average, compared to a standard 1.44 MB floppy's effective ≈16 kB/s and ≈200 ms average ...
Manufacturers have frequently chosen connectors based on factors of size, cost, or convenience at the expense of compatibility. SCSI makes use of cables to connect devices. In a typical example, a socket on a computer motherboard would have one end of a cable plugged into it, while the other end of the cable plugged into a disk drive or other ...
eSATAp cables are available with wide connectors to plug directly into the power and signal connectors of a bare drive, providing a 12 V supply in the case of a desktop machine. A version of this wide connector is found inside every external SATA hard drive enclosure; when the hard drive is slid inside, it mates with a connector that supplies ...
