The μTRON Keyboard (aka microTRON, muTRON, uTRON.) is from Japan, came out in 2007.
μTRON Keyboard is discontinued since .
Total key count: 76.
The μTRON keyboard is a modern version of the TRON TK1 keyboard of Japan.
This is a excellent design. The only design issue i found is that it doesn't have dedicated function keys. The function keys are merged with the number keys. However, the other quality design makes up for it.
- For why the μTRON is a excellent design, see: Keyboard Design Flaws.
- For why dedicated function is important, see: Function Keys in Computer Keyboard.
μTRON Keyboard Layout
μTRON keyboard has 2 modes. Normal mode, and the TRON mode. Normal mode is using standard JIS input method. (which is very inefficient.) TRON mode is based on the TRON Keyboard , a very efficient input method for Japanese. To understand Japanese input methods and what does TRON mode do, see: Japanese Keyboard Layouts
