[Oberon] Maintained open source Oberon/Oberon-2 compiler?

[David Egan Evans]

I have documented as best I can all existing compilers for Oberon, or those directly related, at my website. (Comments for improvement are always welcome.)

There are two strictly Oberon-2 compilers that I know of that are still maintained: Oxford (obc) and Vishap (voc). Both authors have indicated a desire to migrate to Oberon-07. voc will likely be forked for -07, while obc has already added ELSIF in WHILE, etc. while still maintaining code compatibility for the present time.
