Over one and a half years ago, the ussr tag was created, and put on What soviet computer used trinary bits?. It makes some sense on this question, because this question is actually an identify-this-computer question about a machine known to be from the USSR. It's understandable that identify-this-computer wasn't used when this question was asked, since that tag did not exist when the question was asked. The creation of the ussr tag is also understandable, since the only question that had been posted with just the history tag was the tag's test question and a tag about different bit architectures was not as likely to be useful.
For over a year it only appeared on one question.
Less than two months ago, the tag was edited into How were the electronics in the Elektronika IM (Электроника ИМ) designed? by its owner, with the edit description:
Added a tag to my question to clarify that its about Soviet electronics
largely for tagging questions about uncommon hardware by these manufacturers that don't have their own tags.
Except... this question was already tagged with the specific game-and-watch tag. The original Game and Watch series was not made in the USSR, so the tag combination ussr game-and-watch—or any ussr non-ussr-computer combination—is useful only for finding questions about USSR-made clones.
Isn't this a better fit for reverse-engineering, or an entirely new tag?
The tag is also used in How were Western computer chips reverse-engineered in Soviet Russia?, where it was edited in by the same user with the edit description:
Added new tag for the Soviet Union
This seems to be a good use of this tag, as the question is about reverse engineering performed in the Soviet Union.
About 16 hours ago I approved an edit to Were there any LSI-11 like home computers outside of Russia? in lieu of a decision as to whether this tag is useful. However, I now feel that this was a mistake as the question is asking about home computers that are not to do with Russia... and Russia is distinct from the USSR.
Currently its tag wiki excerpt is:
For questions about retro devices from the Soviet Union (USSR)
If we choose to keep this tag, what should we change this to? (Should we change it?)
Also, I couldn't find any other place tags. Would united-states be a useful tag? How about spain for the Inves Spectrum to disambiguate it from the ZX Spectrum? A japan tag for the famicom to disambiguate it from the tag-synonym nes (relevant consensus)? Or is there something special about ussr that makes it more useful than other similar tags?
Is the ussr tag useful?
