The Miyata 1000 had it until 1990 I believe.

Koga Miyata started doing it in either as soon as they started using bottom bracket dynamos ~1981 or soon there after in 1983 or so with the GentsTouring and Traveller. The Randonneur replaced the GentsTouring in 1985 but by then the Koga Miyata model line has exploded and like half of their frames had internal dynamo wiring.
