I think Von Neumann would
agree; he picked 40 bits as I recall. There are all sorts of interesting word lengths out
there; the strangest I've worked with is 27 bits one's complement.
a drum machime?
Not a drum machine. Core memory, all solid state -- one of the first, and as far as I
know the first commercial product with interrupts standard. Electrologica X1, from 1958.
Also its successor the X8, around 1964. The X8 had a drum as a peripheral device, used in
the THE operating system for paging virtual memory (512 k words).
