The 711's read mechanism was based on the IBM 402's and could read 150 cards per minute (250 cards per minute on the IBM 7090).  Announced on May 21, 1952, it was first sold with the IBM 701.  Later IBM computers that used it were the IBM 704, the IBM 709, and the transistorized IBM 7090 and 7094.  Variants of the 711, the IBM 712 and the IBM 714 were used with the IBM 702 and IBM 705 computers.

It was targeted in the Australian market towards the public education sector rather than at consumers, and was sold in three levels: JX (64Kb), JX2 (128Kb) and JX3 (256kb).  Upgrades were available to both 384kb and 512kb.
