Nexgen Nx486SX

[Windmiller]

I found reference to a Nexgen chip called a Nx486SX (SXL /SXF) in some old IBM documnetation, it is only mentioned in passing so I did some searching on found two references, one of them is in German so here is the crappy babelfish translation, its the 6th large paragraph down.

Anyone ever heard of it? Anyway, I was able to find the old Nexgen website using the wayback machine


Here are some of the more interesting pages

Hi,
this chip is not from NexGen but it's a National Semiconductors own design. I think that there is a typo in the original document, here http://www.national.com/news/1996/9611/emb96006emco.html you can find the press release of the National Odin board that use the Ns486sx

I think that it's a typo in the documentation too. The chip's name should be NS486 SXL / SXF

Here is the picture of a NS80486SXL-25 (from my old "for sale" thread)
