Sun

Back in the days, Sun produced PS/2 keyboard with standard 104-key layout (P/N: 3201256-01). What kind of machine it was intended to be used with? Here I've found the pictures.

searching "Sun 320-1256" brings up results mentioning the JavaStation, which did indeed use PS/2 peripherals.

It's not mysterious at all. It's a Sun Type 5C keyboard with a Sun Minidin 8 connector, not to be confused with PS2. The connectors look similar, but the electrical behind it is different. You would need an adapter to use it with a PS2 interface.

These keyboards were sold and used with many sun machines, which specifically I can't remember but I had them on Sun Sparcstations (5s, 10s, 20s), maybe my LX, and various Ultras.

Yup, looks like you're right JavaStation pictures usually include this keyboard.

It is not Sun Type 5c keyboard. Note that Type 5 has non-standard Sun connector and "UNIX" layout while this keyboard has PC layout and PS/2 connector.

zmttoxics: have your eyes checked. the keyboard in the pictures looks different from a Type 5 in almost every way.

xenu: The Type 5 was also available in 'US' layout, and a couple dozen other national layouts. But here the 'UNIX' layout seemed to be the most common.
