=== Apple III ===
The Apple III, released in November 1980, was designed as a business-focused upgrade to the Apple II. It featured a 6502 processor running at 1.8 MHz, 128KB of RAM expandable to 512KB, a 6-bit DAC for sound, and an integrated 5.25-inch floppy disk drive.
Unlike the Apple II, it had a full keyboard with lowercase letters and a numeric keypad, and it featured an 80-column display.
