The Macintosh Hard Disk 20 is the first hard drive developed by Apple Computer specifically for use with the Macintosh 512K.Introduced on September 17, 1985, it was part of Apple's solution toward completing the Macintosh Office (a suite of integrated business hardware & software) announced in January 1985.
The 20SC originally contained a half height 5.25" Seagate ST-225N 20MB SCSI hard drive, but was later manufactured with a full-height 3.5" MiniScribe 8425SA 20MB SCSI hard drive. The latter drive was the same size as the drive inside the Macintosh Hard Disk 20, but 10 to 15 MB over what had previously been offered by Apple for the II family.
The Apple Tape Backup 40SC is an external, SCSI-interfaced, 1 ⁄ 4-inch (6.35 mm) QIC, mini-cartridge tape drive. [2] It was first introduced by Apple Inc. in 1987 and discontinued in 1994. [3] The drive came bundled with Retrospect backup software. [4] [2] [5] The drive is also compatible with the tape software included with A/UX. [6] [7]
A SCSI connector (/ ˈ s k ʌ z i / SKUZ-ee) is used to connect computer parts that communicate with each other via the SCSI standard. Generally, two connectors, designated male and female, plug together to form a connection which allows two components, such as a computer and a disk drive, to communicate with each other.
AppleCD is a range of SCSI-based CD-ROM drives for Mac personal computers, manufactured and sold by Apple Computer from the late 1980s to late 1990s. Earlier AppleCD drives required a CD caddy in order to be used, while later models used a tray-loading mechanism.
Apple HD SC Setup is a small software utility that was bundled with various versions of the classic Mac OS and A/UX operating systems made by Apple Computer.Introduced with Apple's first SCSI hard drive, the Hard Disk 20SC in September 1986, Apple HD SC Setup can update drivers and partition and initialize hard disks.
SCSI interfaces have often been included on computers from various manufacturers for use under Microsoft Windows, classic Mac OS, Unix, Amiga and Linux operating systems, either implemented on the motherboard or by the means of plug-in adaptors. With the advent of SAS and SATA drives, provision for parallel SCSI on motherboards was discontinued ...
Enhanced Small Disk Interface (ESDI) is a hard disk drive interface designed by Maxtor Corporation in 1983 to be a follow-on to the ST-412/506 interface. [1] ESDI improved on ST-506 by moving certain parts that were traditionally kept on the controller (such as the data separator) into the drives themselves, and also generalizing the control bus such that more kinds of devices (such as ...
