Well, I'm not sure the stored program concept was unique to
von Neumann, it
was one of those concepts that was entirely ripe at that
time. Stored program
is meaningless without a decent storage component. Delay
lines had a bunch
of problems, Williams tubes were pretty limited, and drums
were really slow,
but you got more capacity. And, then, of course, core
obsoleted all of the
above, but that was well after the stored program concept
But, something that still bears von Neumann's name is the
concept of a
unified memory for both data and instructions.
The computer in the video clip is the IAS, the cylinders
along the bottom
are Williams tubes, there's a row down each side of the
machine. It is
on display at the Smithsonian.
