I remember this turning up at the arcade near Clarence pier at Southsea. The full hydraulic set up, parked right at the entrance to lure people in.
The queue to get on, and the crowd around it is something I have rarely seen in an arcade to that extent. People willingly shoving in their 50p's (50p for 9 lives or 20p for 3) and rarely getting very far all, while people stood there slack jawed at the graphics. Sure people stood around other games, but not to the extent that Harrier machine attracted when it first went in.
The home conversions were a bit of a let down which was to be expected. Your humble Z80 or 6502 couldn't really replicate a dual 68000 setup with custom graphics hardware.
