Sun Type 5
|This article requires additional photographic illustration — need photos of the switches — what is a "standard" Fujitsu rubber dome? — and the rear case to demonstrate that "Type 5"/"Type 5c" are real Sun model numbers|
|Sun Type 5|
|Years of production||1991—1997|
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 window 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.

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.
