Data General DG/ONE
I worked at DG, and there was a copy of the Spectrum Holobyte version floating around. If you put it on the right machine, you could get the music. Oh, for the good old days of VGA graphics and tinny Russian music! Sad about the authors having to fight so hard for a share of the profits, though. The two of them deserve to be wealthy men.
Great game, my wife is still addicted.
