I found this keyboard randomly on eBay, marked as "AT Russian keyboard, working" or some such. I got it because of the interesting switches, which you can see below in this album.

Interesting for sure. There's a variety of about 4 different versions of the yellow switch on it (OB3, OB5, OB7, and OB1)
And the green switches all appear to be OB3 for the most part.
It has an AT/XT switch as well.
Oddly the ~ and 1 keys don't work despite having no visible damage, yet the ctrl on the left has a damaged switch housing yet works.
Currently cleaning the keyboard.

the switches are all clicky, all the yellow ones have no noticeable differences from each other when typing and the green ones are clicky as well. The greens seem similar to the yellows but I'm not sure if they have different weighting or not. Will check when I can.

*also I don't know if its Russian or Bulgarian but it came from Kiev so probably could be either one*

Interesting thanks for posting! I don't recall ever seeing this combination before.

So I assume the neon greens are a stiffer version of the KPT ambers? You should update the wiki.

Not entirely sure, they seem fairly similar just from typing on them.
Will have to measure them at some point to see the differences.

I'll probably add them to the wiki at some point... still need to post pics of my light blue Space Invader keyboard that is a fairly light, clicky switch. It's good enough to be tied for me with the Model F as my favorite Clicky switch.

The keyboard falls under [wiki]Podworld 292[/wiki]; yours seems to have an earlier revision of the PCB (5 vs 5A), which you can see is very similar, and the switches are the same type. Yours has a different shape case, very similar to that of [wiki]TTI TA-14[/wiki].

OB3, OB5, OB7, and OB1 are mould numbers, and are expected to be a pair of axes, denoting mould and cavity.
