Classic
The Cybiko Classic looks like a walkie-talkie encased in a transparent shell and came in one of six colors (black, clear, yellow, blue, and purple – and a limited promotional red). It has an array of white buttons comprising a QWERTY-style keyboard, joystick pad, and seven function keys. Version 1 (released in April 2000) had a power slide switch on the side, which was later replaced in Version 2, by an software On/Off/Standby via the “Esc”
key. The space saved was used for a manual reset button where the
slide switch use to be.
