As noted by Insidious C., the serial number format is consistent with Pacific Cycles of Taiwan and. indicates a 1987-1988 model manufactured in 1987.
The 26.8mm post size is interesting. It's one size too small for the heaviest gauge, Prestige seat tube but one size too large for Tange #1 and Tange #2. Still, given the post size, it would appear to be a Tange tubeset, either a distorted Prestige or an aggressively reamed Tange #1/#2.
Unicrown forks were definitely available in raod models at this time, though not in Prestige. Based on the unicrown, it's almost certainly an off the shelf Tange fork and should have a alpha-numeric date code on the steering column. That should help to increase confidence as to whether it is a OEM or replacement fork.
The grey to white to pink fade is a typical Miami Vice influenced livery of the era. If it's a later repaint, it's hard to imagine somebody voluntarily choosing this, especially a male. Given, the frame size, I doubt the original owner was female.
