The Power Macintosh, later Power Mac, is a family of personal computers designed, manufactured, and sold by Apple Computer as the core of the Macintosh brand from March 1994 until August 2006.
Lisa is a desktop computer developed by Apple, released on January 19, 1983. It is one of the first personal computers to present a graphical user interface (GUI) in a machine aimed at individual business users. Its development began in 1978. It underwent many changes before shipping at US$9,995 with a five-megabyte hard drive. It was affected by its high price, insufficient software, unreliable Apple FileWare floppy disks, and the immediate release of the cheaper and faster Macintosh. Only 10,000 were sold in two years.
The Macintosh Plus computer is the third model in the Macintosh line, introduced on January 16, 1986, two years after the original Macintosh and a little more than a year after the Macintosh 512K, with a price tag of US$2,599. As an evolutionary improvement over the 512K, it shipped with 1 MB of RAM standard, expandable to 4 MB, and an external SCSI peripheral bus, among smaller improvements. Originally, the computer's case was the same beige color as the original Macintosh, Pantone 453; however, in 1987, the case color was changed to the long-lived, warm gray "Platinum" color. It is the earliest Macintosh model able to run System Software 5, System 6, and System 7, up to System 7.55, but not System 7.52.
The Macintosh II is a personal computer designed, manufactured, and sold by Apple Computer from March 1987 to January 1990. Based on the Motorola 68020 32-bit CPU, it is the first Macintosh supporting color graphics. When introduced, a basic system with monitor and 20 MB hard drive cost US$5,498. With a 13-inch color monitor and 8-bit display card the price was around US$7,145. This placed it in competition with workstations from Silicon Graphics, Sun Microsystems, and Hewlett-Packard.
The Zip drive is a removable floppy disk storage system that was introduced by Iomega in late 1994. Considered medium-to-high-capacity at the time of its release, Zip disks were originally launched with capacities of 100 MB, then 250 MB, and finally 750 MB.
REV is a removable hard disk storage system from Iomega.
Quarter inch cartridge tape is a magnetic tape data storage format introduced by 3M in 1972, with derivatives still in use as of 2016. QIC comes in a rugged enclosed package of aluminum and plastic that holds two tape reels driven by a single belt in direct contact with the tape. The tape was originally 1⁄4 inch (6.35 mm) wide and anywhere from 300 to 1,500 feet long. Data is written linearly along the length of the tape in one track, or written "serpentine", one track at a time, the drive reversing direction at the end of the tape, and each track's data written in the opposite direction to its neighbor. Since its introduction, it has been widely used, and many variations exist. There is a QIC trade association that publishes QIC standards which include interfaces and logical formats. To a very large extent it was the efficiency and openness of this organization which encouraged hardware and software developers to use this type of drive and media.
The ProFile was the first hard disk drive produced by Apple Computer, initially for use with the Apple III personal computer. The original model had a formatted capacity of 5 MB and connected to a special interface card that plugged into an Apple III slot. In 1983, Apple offered a ProFile interface card for the Apple II, with software support for Apple ProDOS and Apple Pascal.
The Ditto drive series was a proprietary magnetic tape data storage system released by Iomega during the 1990s. It was marketed as a backup device for personal computers.
The Power Macintosh 6100 is a personal computer designed, manufactured and sold by Apple Computer from March 1994 to March 1996. It is the first computer from Apple to use the new PowerPC processor created by IBM and Motorola. The low-profile ("pizza-box") case was inherited from the Centris/Quadra 610 and 660AV models, and replaced the Macintosh Quadra series that used the Motorola 68040 processor, Apple's previous high-end workstation line.
The 3480 tape format is a magnetic tape data storage format developed by IBM. The tape is one-half inch (13 mm) wide and is packaged in a 4 in × 5 in × 1 in cartridge. The cartridge contains a single reel; the takeup reel is inside the tape drive.

The Macintosh Quadra 605 is a personal computer designed, manufactured, and sold by Apple Computer from October 1993 to July 1996. The model names reflect a decision made at Apple in 1993 to follow an emerging industry trend of naming product families for their target customers – Quadra for business, LC for education, and Performa for home. Accordingly, the Performa 475 and 476 was sold in department stores and electronics stores such as Circuit City, whereas the Quadra was purchased through an authorized Apple reseller.
The Macintosh Quadra 900 is a personal computer designed, manufactured, and sold by Apple Computer from October 1991 to May 1992. It was introduced alongside the Quadra 700 as the first computers in the Quadra family of Macintosh computers using the Motorola 68040 processor. It is also the first computer from Apple to be housed in an 18.6 inch tall mid-tower form factor, which by 1991 had gained momentum with PC manufacturers as a suitable design for departmental servers.
AppleCD is a range of SCSI-based CD-ROM drives for Apple Macintosh 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. The original model introduced in 1988 was simply called the AppleCD SC. There was also a version of the CD drive that did not have the Apple logo.
Retrospect is a family of software applications that back up computers running the macOS, Microsoft Windows, and Linux operating systems. It uses the client–server backup model.
Magnetic-tape data storage is a system for storing digital information on magnetic tape using digital recording.
Lt. Kernal is a SCSI hard drive subsystem developed for the 8-bit Commodore 64 and Commodore 128 home computers. The Lt. Kernal is capable of a data transfer rate of more than 38 kilobytes per second and 65 kilobytes per second in Commodore 128 fast mode.
The Macintosh Hard Disk 20 was 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 long-awaited solution toward completing the Macintosh Office announced in January 1985. It would be over a year more before Apple would release the file server software AppleShare that would link all of the hardware together. By that time the SCSI interface introduced on the Macintosh Plus in January 1986, would accommodate far faster and more efficient hard drives, rendering the Hard Disk 20 virtually obsolete.
The Apple Hard Disk 20SC is Apple's first SCSI based hard drive for the Apple II family as well as the Macintosh and other third party computers using an industry standard SCSI interface.
