(Many thanks to Simon Wright for building a 64-bit GNAT for MacOS X last

To see a computer of roughly my own age having used highlighting,
in color, making form follow function, and serving intuition
("it's that simple"...) is amazing.
I apologize if this is its least noteworthy feature.
It is spectacular.
It's got separate stacks for separate purposes!
Another of the few insights into the history of wonderful inventions
that market forces have not improved.
Thank you!
You're welcome!
KDF9 does seem to inspire that sort of admiration in people,
Even 50 years after it was designed. 8-)
