Apple II

from year 1977 to year 1993.10 five million sale
8 bit computer

The first Apple II computers went on sale on June 5, 1977[8] with a MOS Technology 6502 microprocessor running at 1 MHz, 4 KB of RAM, an audio cassette interface for loading programs and storing data, and the Integer BASIC programming language built into the ROMs. The video controller displayed 24 lines by 40 columns of monochrome, upper-case-only (the original character set matches ASCII characters 0x20 to 0x5F) text on the screen, with NTSC composite video output suitable for display on a TV monitor, or on a regular TV set by way of a separate RF modulator. The original retail price of the computer was US$1298[9] (with 4 kB of RAM) and US$2638 (with the maximum 48 kB of RAM). To reflect the computer's character cell color graphics capability, the Apple logo on the casing was represented using rainbow stripes,[10] which remained a part of Apple's corporate logo until early 1998. The earliest Apple II's were assembled in Silicon Valley, and later in Texas;[11] printed circuit boards were manufactured in Ireland and Singapore.
