HHKB Professional 2

PD-KB400W

Happy Hacking Professional 2 PD-KB400W

The Professional 2 line was the longest-running model series. The main variation in the Pro 2 line was a built-in low-powered two-port USB hub. PFU later introduced the Type-S variant, a silenced version of the original with silencing rings and a modified slider design to compensate for the loss in travel caused by the silencing rings.
