[Oberon] Building a minimal Oberon

[eas lab]

Very interesting.
This is N-O which is limited to a single partition,
 but can have extra <Aos> partitions for data?
The old versions could access external DOS-files, with difficulty.

What about putting it to a USBstik?
Can you paste & eMail  your output for:
 System.Directory *.Obj
 System.Time
?
