What happened to the ND2510?!

The nd2500, nd2500a, nd2510, nd2510a and all that jazz? Granted the 3500 has “replaced” them, but what about support on their site? I can’t find any technical info about them at all really. What the HECK happened to those drives? Has NEC completely forgotten about them?

I’m looking for a data sheet on the 2510a but can’t find it. Can anyone help me out here?

Well I found what I was looking for, a pox on poorly designed tech companies websites.
