Comparison with Zenith ZKB-2
It is very similar in appearance to the earlier Zenith ZKB-2, sharing case shape and key layout.
Differences from the ZKB-2 include:
- Dye sublimated PBT keycaps
- Blue and green ZDS badge
- Plastic back cover
- XT/AT switch opening in back cover
- Only available with Alps SKCL Yellow switches
Like the ZKB-2, the 163-73 has a piezo keystroke buzzer which emits a short beep/chirp with every keystroke. This feature can be toggled on or off by pressing Alt + ~ (tilde).
The layout is based on the standard 101 key ANSI layout with a few variances. The "Enter" key resembles a square "J" occupying the normal enter position and 1u directly above. The "]}" key is elongated to 1.5u and the "\|" key is relocated as a 1u key to the right of a shortened 1.75u right shift. The Ctrl and Alt keys are 1.75u. The altered keys are highlighted below.
