According to my reading, the Burroughs B5000 and
Manchester Atlas were
both Harvard architecture machines, and the GE-645 was von Neumann. Am
I correct in my interpretation?
On the B5000, one certainly couldn't call the architecture strict
Harvard, I think it'd be a real stretch to call it modified Harvard.
While descriptors differentiated between code and data, these could
be altered under program control. I'd call it more of a protection
mechanism on a von Neumann machine, although that's even an
oversimplification.
