Unique Apple Computer, Inc. cassette tape featuring the company's classic rainbow-striped logo on the label, measuring 4˝ x 2.5˝, neatly signed on the label in black ink by Apple's co-founder, "steven jobs." Handsomely mounted and framed with an Apple Disk II System Manager Package box in an acrylic shadowbox to an overall size of 13˝ x 13˝ x 2.5˝. In fine condition, with some irregular ink adhesion.
Apple introduced its Cassette Interface (ACI) with the Apple-1, which provided the ability to save memory contents onto a standard audiotape, and later load the contents back into the computer's memory. Revolutionary for the time, Steve Wozniak designed the ACI to use only 6 integrated circuits, compared to other solutions which used 50 to 100 integrated circuits. This allowed Apple to sell its solution for less than its competitors; the Apple ACI also operated at four times the speed of its contemporary competitors.
The Apple II, released in 1977, featured built-in cassette inputs and outputs, and cassettes remained popular as a software delivery medium through 1982. Wozniak's development of the Disk II floppy disk subsystem, introduced in 1978, led to cassettes being replaced by floppy disks as Apple's primary data storage format. A remarkable, early piece signed by the great tech innovator.
