[Oberon] FPGA Oberon - DAU status report...

Maybe this is a good time to mention my attempt to get a Python
implementation of the compiler (and RISC) working:

I got pretty far with it before getting side-tracked.  It compiles
Kernel.Mod.txt and FileDir.Mod.txt, but errors with "Reg Stack"on
Files.Mod.txt...  I hope to find time this month to circle back and
finish it.

It was incredibly educational working through the compiler to convert
it to Python.

Eventually I hope to use the Python version of the compiler to
bootstrap the Oberon system on the little RISC emulator I wrote.  The
idea is to be able to play and experiment with an Oberon 2013 system
without an FPGA board.

Warm regards,

"The history of mankind for the last four centuries is rather like that of
an imprisoned sleeper, stirring clumsily and uneasily while the prison that
restrains and shelters him catches fire, not waking but incorporating the
crackling and warmth of the fire with ancient and incongruous dreams, than
like that of a man consciously awake to danger and opportunity."
--H. P. Wells, "A Short History of the World"
