The Happy Hacking Keyboard is a small computer keyboard produced by
PFU Limited of Japan, co-developed with Japanese computer pioneer Eiiti Wada.
Its reduction of keys from the common 104 keys layout down to 60 keys in the
professional series is the basis for its smaller size while retaining full key size.
It returns the control key to its original position as on the early 84 key PC AT
and XT layouts. The current models in production are the Happy Hacking Keyboard
Professional 2, Professional BT, both either dark or light colors, Type-S silenced
variants and blank key caps variants, and the Happy Hacking Keyboard Lite 2
with an additional Macintosh specific variant and a blank variant for each.
