Editing Wang 725-7231-US (section)

==Construction==

===Case===
From above, the keyboard looks the same as the standard 725-3770. However, the differences become apparent when looking at the side profile of the keyboard. It has an additional plastic piece between the top and bottom shell that is loosely connected to the top shell. This is needed to account for the additional keycap height and top plate. Internally the keyboard lacks the distinctive speaker of the normal model, and has a different internal cable system. The keyboard uses the same six screws as the normal Wang, and appears to have the same top and bottom shell as well. This makes sense as it would be far more cost effective to modify the existing 725-3770 shell with additional pieces compared to designing a new mold. The keyboard also uses the same adjustable feet mechanism.

===Plates===
Unique to Tempest keyboards, the Wang 725-7231-US has two plates. They are both unpainted steel, and form a shell around the switches. The bottom plate acts as a normal plate, holding in the switches, and the top plate covers them, allowing the switch stems to poke through. This multi-plate system is undoubtedly an electromagnetic shielding feature.

===PCB===
The keyboard uses a completely different PCB to the standard Wang keyboard. Every single switch pin is bent, which is not a practice employed on most Alps keyboards. The markings and unique construction point to the PCB not being designed by Alps, perhaps being designed by Wang themselves or outsourced to another company. The buzzer is attached to the bottom of the PCB, and there is a ground connector that appears to be scratched off by hand. All of the PCB components are protected by metal shields that do not appear to be accessible. The cable uses a DB-9 connector with 4 pins and extra shielding.

===Switches & Keycaps===
The only known model uses [[Alps SKCM Black|Alps SKCM Bamboo Black]] switches along with two [[Alps SKCL Yellow|SCKL Yellow LED]] switches. The keycaps appear to be the exact same as the 725-3770, with the exception of removable black plastic risers attached between the keycaps and the switches. This is required so that the switches can depress with the top plate in use.
