The von Neumann argument came from the fact that most calculators unlike general-purpose computers stored their programs in a memor y deliberately kept separate from data. In fact the program was stored on the same chips as the data but the calculator manufacturers erected a wall to prevent the twain from meeting. This was done to make the machine easier to use by nonspecialists. A common memor y is often regarded as a central defining feature of a true computer. Another property which most programmable calculators did have was conditional branching the ability to select alternate sequences of instructions based on the results of a previous calculation. That was a property lacking in the machines of the immediate precomputer era the Har vard Mark I the early Bell Labs relay computers and the early Zuse computers. 41.
