Our effort was not to emulate the original hardware, but rather to get 
Oberon running on simple, modern, cleanly-designed hardware.  Since none 
could be found, Prof. Wirth adapted his own (previously virtual) RISC 
processor, using an FPGA as a means to that end.

At the same time, every opportunity was taken to simplify and clarify, 
and get rid of quirks from older days.  For example, it's now an entire 
system built from the ground up in a clear and obvious high-level 
language - no assembler any more.
