Mtec K104 Keyboard. A/X/S Switch... What's the S????

[dabone]

I got a Mtec k104 keyboard this week, and on the underside it has a switch labeled
A X S.

A is At, X is XT (Verified), but what would the S be for? Standard 5 pin din connector.

Here's the deskthority wiki entry.

Ill guess Sanyo... I know Sanyo put out a bunch of XT/AT clones, but used a different keyboard protocol. Given the keyboard AND Sanyo were both made in Taiwan, I think its a good guess.

There's a link on the deskthority page that might give the answer:

It appears likely to be for the proprietary Sun Microsystems protocol. I seem to remember this from awhile back when I used to use one of the earlier models: the K101, I believe. I might still have the manual... I'll have to look.

I'm not very familiar with Sun workstations, but I believe they had proprietary connectors too. If so, it might be that you had to plug in some Sun-to-5 pin din adapter. Someone else here probably knows the answer to that.
