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.
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.
The connector contains two parallel rows of contacts within a shielded case having a characteristic D-shape similar to that used in D-subminiature connectors. The contacts are not pins, but small flat bands of metal, called ribbon contacts. The connectors are manufactured in many capacities, including 14-, 24-, 36-, 50-, 64-, and 100-pin varieties.

Currently known as TIA-530-A, but often called EIA-530, or RS-530, is a balanced serial interface standard that generally uses a 25-pin connector, originally created by the Telecommunications Industry Association. Finalized in 1987 (revision A finalized in 1992 [1]), the specification defines the cable between the DTE and DCE devices.
The connectors developed for its parallel interface live on as the "Centronics connector", used in other computer hardware applications, notably as the printer end of the once ubiquitous parallel-printer cable.
One such in somewhat common use was the VHDCI (Very High Density Cable Interconnect) connector, also known as an "AMP HPCN68M", and sometimes as "SCSI-5". There are 68 pins on the connector in two rows; the pins are 0.8 mm apart. This connector is reputed to suffer fewer bent pins than the 68-pin SCSI-2 connector despite its minuscule pins.
Parallel ATA cables transfer data 16 bits at a time. The traditional cable uses 40-pin female insulation displacement connectors (IDC) attached to a 40- or 80-conductor ribbon cable. Each cable has two or three connectors, one of which plugs into a host adapter interfacing with the rest of the computer system. The remaining connector(s) plug ...
