The theme music for the series was Gioachino Rossini's La Gazza Ladra (The Thieving Magpie)Overture.
I remember scenes of a floppy disc drive spinning up, the head loading and then doing a seek - all very tech and enjoyable.
I recall plot holes even though I was just post teenage at the time. Blowing up (zooming in) on a photograph to extract detail below pixel size gains was one.
It deserved repeating a few times but I felt that it was ignored as the powers that control TV programming seldom (at that time) understood that tech series had a following, as we have seen with the Star trek and Stargate spinoffs.
