Speaking of h/w and f/w, was the model helicopter flight control ever 
ported to Oberon-07?

In Niklaus Wirth, "A Computer System for Model Helicopter Flight 
Control", Technical Memo Nr. 6: The Oberon Compiler for the
Strong-ARM Processor, 1999, we find the following in the conclusion.

    An important advantage of designing one's own compiler is that
    specific, perhaps machine−dependent facilities can easily be
    incorporated. Such facilities are required if, for example, specific
    resources must be accessible, such as processor status register,
    memory management registers, or device interfaces. This is typically
    the case for embedded applications, which also require a predictable
    performance for real−time sensing and control.
