Steve Wozniak

The Apple ][ is an 8-bit home computer, one of the first highly successful mass-produced microcomputer products. Designed primarily by Steve Wozniak, it was manufactured by Apple Computer (now Apple Inc.) and introduced in 1977. It is the first of a series of computers ending with the Apple II in November 1993.

The earliest Apple ]['s were assembled in Silicon Valley and later in Texas. The first computers had a MOS Technology 6502 microprocessor running at 1 MHz, two game paddles, 4 kB of RAM, an audio cassette interface for loading programs and storing data and the Integer BASIC programming language in ROM. The video controller displayed 24 lines by 40 columns of monochrome, upper-case-only text. The original character set matches ASCII characters 20h to 5Fh. The video output was NTSC composite video for display on a TV monitor or a regular TV set through a separate RF modulator. The original retail price of the computer was $1,298 (with 4 kB of RAM) and $2,638 (with the maximum 48 kB of RAM). To reflect the computer's color graphics capability, the Apple logo on the casing used rainbow stripes, which remained a part of Apple's corporate logo until early 1998.

This is an original Apple ][, not the Apple ][ Plus. It runs integer basic, so if you print 5/2 the answer will be 2, not 2.5 (need an Apple ][ Plus for floating point arithmetic).

Steve Wozniak signed our Apple during his trip to Baltimore in January 2014.
