IBM
IBM 1401 – 1959
2nd generation
 The all-transistorized IBM 1401 Data Processing System
placed the features found in electronic data processing
systems at the disposal of
1402
1401
1403
smaller businesses,
previously limited to the use
of conventional punched
card equipment
 These features included: high
speed card punching and
reading, magnetic tape input
and output, high speed
printing, stored program, and
arithmetic and logical ability
