The Happy Hacking Keyboard is a small computer keyboard produced by PFU Limited of Japan, co-developed with Japanese computer pioneer Eiiti Wada.[1] 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[2] in production are the Happy Hacking Keyboard Professional 2,[3] Professional JP,[4] 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.

Happy Hacking Keyboard Lite 2 with 68 labeled keys.

Common features

Some of the Happy Hacking Keyboard design tenets, as dictated by Wada, include a minimal 60 key design, no cursor or function keys, and standard keyboard pitch, all optimized for use in UNIX environments.[5]

Happy Hacking Keyboards lack a numeric keypad, and keys outside the typewriter key area are mainly accessible through the Fn key. The keys are arranged in a layout resembling the Sun Type 3 keyboard. Specifically:

  • The control key is found where most keyboards place the caps lock. This is the only control key on the keyboard.
  • The esc key is located to the left of the 1 key; the tilde key normally found there is at the right end of the same row.
  • The delete key is located directly above the enter key; the key normally found there is the second rightmost key on the row above it. Furthermore, this is an actual delete key, not a historically named backspace. Backspace is accessible through Fn+Delete.
  • The meta keys are located between the space bar and the alt keys.

On the far side of the keyboard there are DIP switches. These may be used to:[6]

  • Turn the delete key into a backspace. Fn+Delete remains backspace, and Fn + top-right key remains delete.
  • Swap the alt and meta keys.
  • Enable/disable downstream USB ports on USB models.

Its size fits half the size of a DIN A4 paper.
