	On a related tangent, my nomination for "Least Wimpy
	Memory" was the core on a 360/91.  When UCLA's 91KK
	arrived in 1968, its 4 megabytes of core made it one
	of (I think) the 2 biggest machines in the world.

	This isn't "big" just in megabytes; the core sat in what
	we'd now think of as "giant" boxes at opposite ends of
	the CPU.  It used so much power that it was water-cooled,
	via copper plumbing under the machine room's raised floor.

	... And at least once the machine went down because
	the plumbing sprang a leak.
