[Oberon] Model Helicopter reports

[jwr at robrts.net]

In trying to find the various original Oberon language reports, I  
discovered several of the reports regarding "A Computer System for  
Model Helicopter Flight Control", in particular "Technical Memo Nr."  
1, 2, 3, and 6, and a bibliographic reference to 4.  What was number  
5?  Is there one beyond 6?  Is number 4 the same as eth-4357-01.pdf  
"Technical Report Nr 314"?


Files I found include:

"A computer system for model helicopter flight control, Technical memo  
Nr. 1: the hardware core", Niklaus Wirth, January 1998, 284, 15.12.97
https://e-collection.library.ethz.ch/eserv/eth:4326/eth-4326-01.pdf
https://www.inf.ethz.ch/personal/wirth/Oberon/284.pdf

"A computer system for model helicopter flight control, Technical memo  
Nr. 2: the programming language Oberon SA", Niklaus Wirth, January  
1998, March 1999 Second Edition, 285, 21.12.97 / 15.1.99
https://e-collection.library.ethz.ch/eserv/eth:4327/eth-4327-01.pdf

"A computer system for model helicopter flight control, Technical memo  
Nr. 3: the software core", Marco A. A. Sanvido, April 1999, 317,
https://e-collection.library.ethz.ch/eserv/eth:4358/eth-4358-01.pdf

"A computer system for model helicopter flight control, Technical memo  
Nr. 6: the Oberon compiler for the strong-ARM processor", Niklaus  
Wirth, March 1999, 314, 7.3.99
https://e-collection.library.ethz.ch/eserv/eth:4355/eth-4355-01.pdf

"Software for Model Helicopter Flight Control", Markus Kottmann, March  
1999, Technical Report Nr 314
http://e-collection.library.ethz.ch/eserv/eth:4357/eth-4357-01.pdf

Within Tech memo Nr 3 by Marco A. A. Sanvido, bibliographic reference  
number 5 is to:
M. Kottmann, A computer system for model helicopter flight control,  
Technical Memo Nr. 4: The autopilot software, February 1998
Is that the same as the Markus Kottmann report above  
(eth-4357-01.pdf), or a different one? I think it is a different one.

Where can one find copies of model helicopter reports 4, 5, and any beyond 6?
Are there any other Oberon-related model helicopter reports which are  
named or numbered differently?
