I always thought the DDR version of the GeForce 256 was released in 2000. Then someone posted their December 23, 1999 receipt for GeForce 256 DDR. Now I've gotten my hands on a GeForce 256 DDR with 1999 manufacturing dates on everything.
This isn't definitive; I can't say when every part of this card was made, and I have no idea how long it took them to get this card into retail channels after manufacturing was finished. But it is suggestive.
