> Native Oberon System 3 Release 2.3.6 (Stand-alone):

Release 2.3.6 was 1999-05-13.  In Alpha, dated 2003-01-05, which is 
running here, these are the first 12 lines of SYS:Native.Tool as plain text.  
Notice Kernel.Mod on the 12th lne.  To see colors and links, open 
SYS:Native.Tool on your system.

MODULE Kernel;	(** non-portable *)	(* rc/ard/nm/jm/jdv/pjm/rml*)

(** Module Kernel is responsible for memory allocation, garbage collection and other run-time support for the Oberon language, as well as interfacing to the underlying machine.  Using features exported from module Kernel may result in an unportable module, as not all Oberon Kernels are the same. This module is of little importance to most Oberon programmers. *)

The kernel source was not released for 2.3.6 but was released for Alpha?  
In any case, Alpha is the preferred system and absence of the older kernel source 
shouldn't be detrimental.

> The source for Oberon0 is very hard to get ...

In Alpha, creating a fresh Oberon0 diskette with support for CF is a simple exercise, 
thanks to instructions from Josef Sedlacek.  
Click here.  Desktops.OpenDoc "http://142.103.107.138/OberonPage.html#Files"
And here.  Desktops.OpenDoc "http://142.103.107.138/OberonPage.html#ATADisks"
And continue with more clicks therein.

Analogous modifications can be developed to add support for other hardware to Oberon0.

Any feedback concerning my notes is always welcome.

Regards,                 ... Peter E.
