What is Cyrix 486? What is the relationship btn NeXTStep & 486?

[Wong Sai Kee (Graduate Assistant)‏]

As I did not read news on NeXTStep and 486, I lost tracking. Would
anybody give me pointers/information about "What is Cyrix 486 ?" &
"What is the relationship between NeXT, NeXTStep and 486" ?

In order to save netnews bandwidth, you could send me via email.

Thanks
