  IBM 701
The IBM 701, known as the Defense Calculator while in development, was announced to the public on April 29, 1952, and was IBM’s first commercial scientific computer.
A Fortran compiler was not released by IBM until the IBM 704.
The successor of the 701 was the index register-equipped IBM 704, introduced 4 years after the 701.

 IBM Archives: 701 Translator
The first step in preparing IBM's magical computer to repeat this human performance of a mechanical task was to write electronically, in plus and minus charges on a magnetic drum surface, 250 Russian words and their equivalents in English.
The second step in preparing the 701 to translate was to store the detailed instructions -- exactly like those the people in Washington had followed, except that these were written in electrical charges on the faces of cathode ray tubes in the 701's electrostatic memory.
What IBM's astonishing 701 actually did, in executing the Russian-English translation, was to create within itself a working model of another "brain" specially designed to handle logic instead of mathematics.

 Fifty years of IBM innovation with information storage on magnetic tape
The IBM 729 Model III, with the introduction of pairs of three-position assemblies which moved pinch rollers that allowed the tape to be engaged by the appropriate capstans, called prolays, allowed improved start-stop performance and a significant reduction in mechanical complexity.
As the 20th century drew to a close, the IBM LTO was announced, and a new technology roadmap began for tape [17].
The IBM LTO Model 3580 head was the first IBM tape drive recording head to break away from the older modular closed and contoured head designs that had carried the burden of linear tape drive recording for so long.

 The IBM 700 Series
The scientific line consisting of the 701, 704 and 709 were 36-bit binary machines with an accumulator architecture.
The earlier 701 (introduced in 1951) and 702 used Williams tube memory, the later machines all used core memory.
The 701 and 702 used drives capable of 100 bpi, while all the later machines used drives that worked at 200 bpi.

 One Real Machine: The IBM 701
Of the early stored-program computers, the IBM 701 Defense Calculator is one that had random-access memory, although implemented with Williams tubes and not core, and which had a particularly simple and straightforwards instruction set.
Incidentally, with sign-magnitude notation, carry out of the magnitude portion of the number constituded an overflow, so the overflow bit was considered to be placed between the sign bit and the magnitude bits of the conventional quantity in the accumulator.
And the IBM 701 was the first of a long line of IBM computers whose first digit was a 7.
