Zenith ZA-180-89 is a standalone numeric keypad designed to interface with Zenith Data Systems's range of notebook computers, such as the Zenith Supersport SX.

Description

In addition to the usual grid from num lock down to enter, the keypad features the F11 and F12 function keys that are absent from the Supersport SX. There is an additional, isolated column on the left of the keys that can only be accessed using the Fn key on the Supersport: Scroll lock, Home, End, Page up, and Page down.

Despite being a companion product for their notebook line, the ZA-180-89 bears numerous differences to the Supersport SX:

• Integrated LEDs in the lock keys using Alps common mount low profile switches, instead of discrete LEDs (the other keys use Alps integrated dome switches as with the Supersport SX)
• Bare black PCB, instead of brown PCB with a foam mat
• Dye-sublimated legends, instead of double-shot with pad printed secondary colours

The PCB carries Alps's branding on the trace side, and "MADE IN JAPAN" on the top.
