IBM Xenix 2.0 Compatability

[Robert James]

I recently acquired a copy of IBM XENIX 2.0.  My plans were to use this
software to get a basic knowledge of the UNIX/XENIX environment and basic
playing around...

The question is...are there any BIG differences between this software and
the current SCO release of 286 XENIX such that the basic OS concepts I may
learn from this 'dated' software would no longer apply today?
    
Thanks for any responses...
