You're right that the 36-bit machines rely heavily on octal notation.
However, Unisys has not exited the hardware business.
The descendants of the original 36-bit 1100-series machines are now
called Dorado. Unisys announced new models as recently as May 2009
I have the extreme pleasure of supporting a Dorado 180 and writing
Python code on Windows--the best of both worlds!
