I think you dad may have invented a time machine also as that isn't from the early 90s, it's from the very late 90s (probably 1999).
The bike has the steerer stop that was introduced to reduce the dual crowns hitting the boom tube, it has the last version of the seat mast and the bolt on cable routing all indicating late 90s. Those forks weren't available til 98/99 likewise the wheels, the saddle the seatpost, the stem, the bars, the tyres....
