The Apple ///+ was released in December 1983 at a price of US$2995. This newer version of the Apple /// included a built-in clock, video interlacing, standardized rear port connectors, 55-watt power supply, 256 KiB RAM as standard, and a redesigned, IIe-like keyboard. Apple discontinued the Apple III series on 24 April 1984, just four months after introducing the III Plus, after selling 65-75,000 computers and replacing 14,000 defective units.

Owners of the Apple III could purchase individual III Plus upgrades, like the clock and interlacing feature, and obtain the newer logic board as a service replacement. A keyboard upgrade kit, dubbed “Apple III Plus upgrade kit” was also made available – which included the keyboard, cover, keyboard encoder ROM and logo replacements. This upgrade had to be installed by an authorized service technician.
