I got this for free from Zeppelin along with some other keyboards (which I will post later):
MICRO USA.
Some keys look as if they went too hot and melted slightly. Please notice the Yogoslavian layout.

Cool, Honeywell Hall Effect switch.
1K3S

No idea what the K is for, but the rest of the numbers are known. The K position is for the stem type, so please take lot's of pictures of the switch so I can update the wiki.
Also, make sure to check all of the switches, since sometimes there are different switches for different keys, and it would be neat to get some more switch codes

I wonder what the two missing keys where labeled.webwit wrote:Admin keyboard. Sounds authoritative.
Escape and ...?
There is no Control key, but PA1-PA3 and other keys which are familiiar to me (e.g. 3270) but on the other hand, there is Alt key.
I really have to learn more about how these keyboars where used and to which machines they had been connected ...

All the current numbering on the wiki is based on theories by me. In the past I haven't had much luck getting through to Honeywell. I did manage to get the keypad data sheet on one attempt though.
Interesting, I think the sticking out part of the switch is what makes it a K. It's similar to one of the LED switches.
