|Years of production||1991—1997|
The Sun Type 5 is a keyboard that was made for Sun SparcStation line. It is the successor of the Sun Type 4 and the predecessor of Sun Type 6. The keyboard has been heeded by many as being the most beautiful keyboard in the world.[Citation needed] Earlier production units only had the Sun chain logo.
The exterior is in Sun's colour scheme of light grey and purple. The keycaps are of higher quality than typical Fujitsu keyboards: sharp-edged, dished and with dark blue letters. Caps Lock, Num Lock, Scroll Lock and Compose each has a small windows for a LED. All keys do not have the same hue: modifiers are in the same light grey tone as the case while the alphanumeric keys are white.
There are a few variants, with either:

The Space Bar row has keys:
|Control (or Caps Lock)||Alt||Meta||Space Bar||Meta||Compose Character||Alt Graph|
Cable and protocol
The protocol is Sun's proprietary. The signaling is based on RS232 at 1200 baud.
The first version had a connector for a detachable cable on the left and right sides, where the other port could be used for a Sun mouse. The Sun Type 5c has a fixed cable and dedicated Sun mouse port in the middle of the underside with cable channels for both cables going to the left and right.
Use with modern computers
- Because the signalling is based on RS232, a typical serial port could be used together with the right cable and drivers.

Hobbyist attempts have been made to reprogram a RS232-to-USB converter into a keyboard converter. Another Swedish enthusiast has made a new controller that speaks PS/2. Protocol converters have also been spotted for sale in a shops in the Akihibara district in Tokyo, Japan.
