In May 1965, NEC marketed the N209A-2 Paper Tape Input Unit for the NEAC Series 2200.
This unit enabled reading of 5- to 8-row tape, and was equipped with reels for tape handling, so it was suitable for high-volume data processing. Vacuum columns were provided as tape buffer storages between the reader part and the tape reels, and the system achieved a tape read speed of 1,000 characters per second by performing reel motor control to suit the amount of tape.
