thanks Len, that observation of your seeing the new Honeywell DDP 516
demonstrated at what you believe was the Full joint computer conference of
1968 being suspended from the ceiling with wires connected to the hooks on
top of the IMP would seem to "settle the issue" as to the "nature and
origin" of the hooks -- in that they were most likely innate to the cabinet.
