Mine is: GNU/LINUX OberonTM  V4.0-1.7.02 Linz RLI
I've only seen one system which writes white-on-blank, 
and it looked spooky.  But I suppose it uses less power.
IIRC I patched the Source to Save in *nix format, but I didn't 
bother to change the [button-Label] and the log still shows:
'EditTools.StoreAscii /tmp/ObnTmp  921'

The one small difference that I liked about V4 is that it auto-detects
if the file to be loaded is in Obn or *nix format. So that I can use
MM/MR to load all file types.

New stuff like wireless is mostly made in Asia, where they think 
in terms of 'market share', so they cater only for MicroSoft.

OTOH the linux could handle all the networking and allow V4
to be the front end.
I recently noticed in V4: Mailer.Mod -> PROCEDURE Send*; ...
		Texts.WriteString(W, S.s); Texts.WriteString(W, " mailing");
		Texts.Append(Oberon.Log, W.buf);
		cmdStr := "(/usr/lib/sendmail -oi -t < /tmp/Mailer.Send; rm
/tmp/Mailer.Send) &";
		Unix.System (SYSTEM.ADR(cmdStr), LEN(cmdStr));
		(* Unix.System("/usr/lib/sendmail -oi -t < /tmp/Mailer.Send"); *)
		(* Files.Delete("/tmp/Mailer.Send", res) *)
END Send; 
So V4  writes the text to a file and calls *nix `sendmail` to handle it.
Since sendmail does 'everything', it would handle eg. TxAuthorisation
which Oberon lacks. OTOH sendmail is known to be a monster to setup.
So now I have to save this, written in LEO, as *nix and paste it into
a *nix mailer which handles the TxAuthorisation.
