Hard disk drive connector :
Teletype Impulse provides a broad array of disc drive connectors. Our connectors are R Ohs compliant and are being used on most major platforms around the world. Teletype offers its cone point technology to insure maximum connectivity performance, and high temperature plastic materials are common. Telephone's products are designed to meet the global requirements of the computing industry. Custom design configurations are available upon request.
Several different connectors and jumpers are used to configure the hard disk and connect it to the rest of the system. The number and types of connectors on the hard disk depend on the data interface it uses to connect to the system, the manufacturer of the drive, and any special features that the drive may possess. Instructions for setting common jumpers are usually printed right on the drive; full instructions for all jumpers will be in the product's manual, or on the manufacturer's web site.

Hard disk drives were introduced in 1956 as data storage for an IBM real time transaction processing computer and were developed for use with general purpose mainframe and mini computers.
As the 1980s began, hard disk drives were a rare and very expensive additional feature on personal computers (PCs); however by the late '80s, hard disk drives were standard on all but the cheapest PC.
Most hard disk drives in the early 1980s were sold to PC end users as an add on subsystem, not under the drive manufacturer's name but by Systems Integrators such as the Corvus Disk System or the systems manufacturer such as the Apple ProFile. The IBM PC/X in 1983 included an internal standard 10MB hard disk drive, and soon thereafter internal hard disk drives proliferated on personal computers.
External hard disk drives remained popular for much longer on the Apple Macintosh. Every Mac made between 1986 and 1998 has a SCSI port on the back, making external expansion easy; also, "toaster" Compact Macs did not have easily accessible hard drive bays (or, in the case of the Mac Plus, any hard drive bay at all), so on those models, external SCSI disks were the only reasonable option.
