The only Free UNIX I've seen, besides the offering from SUN would be the older UNIX source code released from SCO, their 'Ancient UNIX.' Not sure how much use it would be for you, but it is 'Free' UNIX.

this just goes to show how loosely the term Unix can be used.. infact i am guilty of the same mistake... !
last year when I started learning unix\/linux i was obsessed with learning unix not linux and didn't know till about a couple of weeks ago that Free BSD Unix is basically open source.. I didn't even know what open source was till my brother pointed out that I was trying to download open source software mainly used for servers.. . and as silly as it seems I completely refused to believe that linux is unix and that linux is anything worth while..which as woofies link mentions is competition.. and this is for a reason. there is real power in linux-unix
