No confusion.  I don't find much need to use assembly since the speed of 
modern MCUs are much faster than they were when the RTX2000 was 
designed.  There is also a wide range of processors out there that will 
run at very high speeds.  If I need a faster processor, I use a faster 
processor.

MPE has a clean room implementation of the RTX.  I'm sure they charge 
for it or I would be interested n playing with it.  FPGAs allow many 
things to be studied that would have required a full eval board at one 
time.  FPGAs are cheap and common as evidenced by Ting's workshop in 
FPGA development being presented at SVFIG.
