When the original Macintosh was introduced in January 1984, this Numeric Keypad was also announced as an accessory for an additional $99. The keypad uses the same telephone-cord-like interface as the Macintosh to attach in a daisy chain to the keyboard or computer.
The exterior packaging, included with this example, uses a stylistically similar “Picasso” abstract rendering of the product and Apple logo as the packaging of the original Macintosh.
The interior packaging is white styrofoam with an embossed Apple logo.
