What kind of Used Unix system to buy? 2

[JMPEL34]

Hi,

I'm just a basic PC user, with a CAD background. I start a new job using using various CAD and Nesting software with Unix as the OS.

My Question is this: I'm looking to buy a used Unix system just a mini tower. Any suggestions about the type/brand to get or stay away from would be great.

I'm going to use it at home for training myself. Is Redhat similiar to Unix I'm not sure the direction to go at this time.

Thanks,
Rob

So my MAZDA is different from my girlfriend's Mazda?

Hmmm. The FreeBSD website posts this statement:
"...It is derived from BSD, the version of UNIX® developed at the University of California, Berkeley..."

BSD is Unix, but they cannot use the Unix name because of the Open Group and licensing or whatever. It may have been part of the legal settlement, too, but yes BSD is Unix.

I believe that Unix is more of a philosophy that a concrete implementation. But there's a lot of grey area, is Window NT a reimplementation of VMS? It could be argued.

My biggest point was there is a UNIX and a Unix.

That is ridiculous.

Though Mac and windows users regularly argue that there is no semantic difference between thisfilename and ThisFileName. I think they should think about this argument the next time they Polish their car.

Linux (and, to my knowledge, the recent BSDs) aren't backed by big companies with the money to pay for those tests, so they can't be officially called UNIX(TM). They are instead called Unix, which basically means that they're close enough, but haven't paid for the tests.

Not to nitpick, but that's not quite true anymore.
SuSe is fully owned by Novell, IBM has a big stake in Redhat.
While both may not have an interest to get the official certification they certainly have the money
