Apple ProFile

Apple ProFile

The ProFile was the first hard 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 ProDOS and Apple Pascal.

Also in 1983, Apple introduced the Lisa computer, which was normally sold with a ProFile. The ProFile could be connected to the built-in parallel port of the Lisa, or to a port of an optional dual-port parallel interface card. Up to three such interface cards could be installed, so in principle up to seven ProFile drives could be used on a Lisa.

The 5 MB ProFile was Apple's first hard drive, and was introduced in September 1981 at a price of US$ 3499. Later a 10 MB model was offered, but required an upgraded PROM/interface card to recognize the additional 5MB.

Internally, the ProFile consisted of a bare Seagate ST-506 drive mechanism, without the usual Seagate electronics, a digital and an analog circuit board designed and manufactured by Apple, and a power supply.

Later Lisa models could be configured with an internal 10 MB "Widget" drive designed entirely by Apple, but the Widget was never offered as an external product for use with other Apple computers.

Apple did not offer another hard drive until it released the Hard Disk 20 designed specifically for the Macintosh 512K in September 1985 which could not be used on the Apple II or III families, or Lisa series. By September 1986, the ProFile would be superseded by the introduction of the first Hard Disk 20SC SCSI-based drive and interface card for the Apple II family.
