- Through the wonders of unix, wherein the same code was for the most
- part still usable, with substantial speed improvement. It's fairly
- hard to do that with hardware dependent operating systems like dos,

- It doesn't need to, because at the time those chips were made, the
- market was not there for upgrading, etc. If you bought new computers,
- they were new, and you started over. Now people have an investment in
- their machines to such an extent that starting over would be
- prohibitive.
