With a variety of models and special features available for the IBM 1440, a system could be tailored to meet immediate data processing requirements of the business and expanded to absorb increased demands as needed. Programs for the 1440 could be easily adapted to run on the IBM 1401.


The basic system consisted of:

  • IBM 1441 Processing Unit contained core memory, arithmetic and logic circuits
    • Up to 16,000 alphanumeric storage positions were available
  • IBM 1447 Operator's Console
    • Model 1 provided basic processing control for the system
    • Model 2 added an electric typewriter

The following peripherals were available:

  • IBM 1412 Card Reader/Punch
    • Model 1 read up to 300 cards a minute and punched up to 80 columns a second
    • Model 2 read up to 400 cards a minute and punched up to 160 columns a second
  • IBM 1443 Flying Typebar Printer
    • Basic rate of 150 lines a minute and up to 430 lines a minute, depending on typebar
    • Interchangeable typebars having character sets of 13, 39, 52, and 63 characters
  • IBM 1311 Disk drive
    • Capacity for 2 million characters in each removable pack
      • With optional "Move Track Record" feature, capacity is increased to 2,980,000 characters in each pack
    • Each pack weighed less than 10 lb.

Floppy disk - Wikipedia, the free encyclopedia (10412 words)
In 1967 IBM gave their San Jose, California storage development center a new task: develop a simple and inexpensive system for loading microcode into their System/370 mainframes.
The 370s were the first IBM machines to use semiconductor memory, and whenever the power was turned off the microcode had to be reloaded ('magnetic core' memory, used in the 370s' predecessors, the System/360 line, did not lose its contents when powered down).
IBM developed, and several companies copied, an autoloader mechanism that could load a stack of floppies one at a time into a drive unit.
