[Oberon] Particularly Useful Oberon Implementations

[jwr at robrts.net]

As stated in my previous message, in December I purchased an  
OberonStation, and am currently trying to understand which  
implementations of Oberon (in addition to that of Project Oberon 2013)  
are also valuable to obtain and study.  I am also interested in those  
valuable to USE: implementations which provide certain features or  
tools useful for programming, documentation, data conversion or  
transfer, networking, drivers for particular devices, etc.

It currently appears to me that the following are particularly useful  
(for my purposes).  I am interested in feedback concerning these and  
others you think valuable for particular reasons.

I remain fairly puzzled regarding exactly which version numbers,  
release dates, and download locations are most appropriate for study  
and use of ETH Oberon / LEO / NO / LNO / ALO.

Are other versions of AOS/UnixAOS/Bluebottle/A2 particularly useful?

Of note, http://oberon07.com/compilers.xhtml is a useful list of  
various Oberon compilers.
