Magic Keyboard with Numeric Keypad (US English, Space Gray, 2019)

According to Apple:

The “Magic Keyboard with Numeric Keypad features an extended layout, with document navigation controls for quick scrolling and full-size arrow keys for gaming. A scissor mechanism beneath each key allows for increased stability, while optimized key travel and a low profile provide a comfortable and precise typing experience. The numeric keypad is also great for spreadsheets and finance applications. And the built-in, rechargeable battery is incredibly long-lasting, powering your keyboard for about a month or more between charges.” 

The keyboard used a Bluetooth connection and shipped with a Lightning cable for charging. It was 0.16–0.43 inches high, 16.48 inches wide, 4.52 inches deep, and weighed 0.86 pound.

This Space Gray color was discontinued some time in Summer 2021.

Numeric Keypad (for original Macintosh, M0120, 1984)

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.
