Abstract: To record data originating at rather high input rates (a billion counts/sec) — rates currently outside the range of feasibility for magnetic-recording media such as high-speed tapes, discs, drums or core memories — fast-framing cameras offer a feasible alternative at low cost. Data are recorded and directed into integrated circuit scalers associated with each of 334 channels. The twelve data lines of each scaler are read out simultaneously in a group of 56 scalers into a panel of neon lamps; the lamps fire if a “one” bit is present and remain extinguished for a “zero” bit. The resulting pattern of lights reflects the stored data. With the aid of synchronizing pulses, the panel is gated to display one of six groups at the moment the shutter is open. An existing film-scanning station has been adapted to translate the developed dot images from 16mm film into computer-compatible magnetic tape.
