Tom's Hardware Guide published a review on Topre RealForce 104UW Keyboard
A quote from the article:
We review the Topre RealForce 104UW. Topre, a contraction of its former company name ?Tokyo Press Kogyo,? is a Japanese engineering company that has been making plastics and metal components since 1935. However, it also makes electronics, and the company has made a name for itself in the keyboard community for the Topre capacitive switch. These are famously used in the Happy Hacking Keyboard (HHKB) and Realforce lines of keyboards, the latter of which we?re looking at today.Topre RealForce 104UW Keyboard Review @ Toms Hardware
