I have told you
There are many things didn’t work from fabric in the Soviet Union, and we didn’t replace or return these, had warranty repairs only.

Computer class for robotic education consisted 12 DVK-3M/4 computers with MC7004 keyboards. I took part in unboxing and installation. 4 keyboards didn't work from the box. Another keyboards worked unstable - repeat symbol 2 or 3 times on key pressed once or didn't generate symbol until key pressed ...

I wouldn't recommend to use it for work!
The keyborard was made for pdp11 compatible computers DVK and Elektronika-85. In real life 4 from 12 new keyboard didn't work and others work unstable. Technically it's use LK201 interface.

Oh!
This is definitely Hungarian Videoton keyboard.
It was connected to terminal (VDN-52500, VDX-52600) or VT-16 PC.

I have almost the same keyboards from VDX-52600 but with RAFI switches and Russian key caps. The case is the same, board and layout are very close.

VDN-52500 uses the same switches ...

This keyboard from Videoton VDN-52500 terminal
