Burroughs, AKA Unisys, designed a machine called the "D" machine,
around the early to mid ''70s.  We had a prototype here at Illinois.
It had a nanomemory.  (Damn thing was designed so the nanomemory board was
symetric, you inserted it one way and it worked, insert it upside down
and it burned out. We didn't have it very long.)  I'm not sure if it ever made
it to the marketplace--in my memory I associate it with the 1800;
that was either it's final name or the machine that won out over it--
it probably died along with the FMP and BSP.  For a free Convex I might be
able to dig up a manual...

	There once was a machine from Urbana
	Built in a poolside cabana...
