I noticed the question was asked (but not answered): what is the largest 
storage capacity found in drums?  I commented that it's at least 512k 27-bit 
words, which is the size of the Electrologica X8 drum, circa 1970.

That reminded me the TU Eindhoven replaced their X8 by a Burroughs 6700 system, 
which also had a drum.  I remember a cube about a meter wide.  But I don't 
remember its capacity and can't find anything on Bitsavers that even mentions 
drums on any Burroughs mainframe.  Does anyone know?
