[Oberon] Does anyone have the missing source files of Oberon System 3 v2.3.6?

[Rochus Keller]

Hello everyone

Both archives referenced in https://en.wikibooks.org/wiki/Oberon/ETH_Oberon/download 
under Native Oberon Native/StdAlone/ and Native/Update/Beta/ (which seem to be identical anyway)
are lacking the Kernel.Mod, Modules.Mod and the OP2 compiler source files (Compiler.Mod, OP*.Mod). 
Does anyone have and is willing to share these source files? I'm looking for the exact version of these 
source files which was used to generate the included object files.

Best regards
