"Дельта-С", a soviet clone of ZX Spectrum 48k
Today is 23rd of April 2022 and it's ZX Spectrum 40th anniversary!
While I don't have an original 48k model, I do have it's clone - а soviet "Дельта-С" personal computer. It was a present to me from my dad back in 1991, and this computer is still in fully working condition.
