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|
|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.
There are a few variants, with either:
- More IBM-like layout, including ISO layouts.
Tenkeyless variants were also made[Citation needed].
To the left side, there is a cluster of named function keys:
The space bar row takes one of these forms:
|Caps Lock||Alt||Meta||Meta||Compose||Alt Graph|
Cable and protocol
The protocol is Sun's proprietary. The signalling is based on RS-232 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. Sun Type 5c has a fixed cable and a 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 RS-232, a typical serial port can be used coupled with the right cable and drivers.

Hobbyist attempts have been made to reprogram a RS-232 to USB converter into a keyboard converter. Another Swedish enthusiast has made a new controller that speaks PS/2[Citation needed]. Protocol converters have also been spotted for sale in a shop in the Akihibara district in Tokyo, Japan.
