The return to the active service of tanks not-modernized is also a fact in Russia today.
When things are taken out of storage it is standard procedure to fully check they are completely operational, but normally they are fitted with new equipment and systems.
A tank from 1985 would need quite a few upgrades and changes before it would be useful in service today... the audio cassette tape would be replaced by a solid state flash RAM system for instance.
Even just to make it easier to operate and maintain, certain obsolete components would be changed and communications and optics would also be changed.
