I'm with T-Mar 1986 or even later, '87. Scott "tri" bars on it. No comment on the bars style. Do consider if you are in the Aero position the time it takes to get to your brake levers, rate x time = distance, you could easily lose 20 feet before you could apply the brakes.
The current mix of components on it is pretty well balanced aside from the freewheel ratio perhaps.
Most "Forks-R-Us" Carbon forks will probably have less rake and length from crown seat to axle may also be different, crown race diameter may also be different the existing headset may be loose on the new fork. Could work out, could be scary.
