  IBM 1620
A modified version of the 1620 was used as the CPU of the IBM 1710 Industrial Process Control System.
IBM could only build one of the two and the Poughkeepsie proposal won because "the San Jose version is top of the line and not expandable, while your proposal has all kinds of expansion capability - never offer a machine that cannot be expanded".
Following announcement of the IBM 1620 on October 22, 1959, due to an internal reorganization of IBM, it was decided to transfer the computer from the Data Processing Division at Poughkeepsie (large scale mainframe computers only) to the General Products Division at San Jose (small computers and support products only) for manufacturing.

 IBM 1620 - Wikipedia, the free encyclopedia
The IBM 1620 was announced by IBM on October 21, 1959 and marketed as an inexpensive "scientific computer".
The successor to the 1620, the IBM 1130 was based on a totally different, 16-bit binary architecture.
In some 1620 installations it was called a SMERSH, as used in the James Bond novels that had become popular in the late 60's.

 IBM 1620 Model I
The IBM 1620 I was the original implementation of the IBM 1620, introduced in 1959.
This unit (commonly called 1620 until the Model II was introduced) was produced as inexpensively as IBM could make it, in order to keep the price low.
It did not even have conventional ALU hardware: all arithmetic was done by table lookup in Core memory.

 Saga
In September 1960 the representative of IBM in Iceland, Ottó A. Michelsen, wrote to the Faculty of Engineering at the University of Iceland, and to the National Research Council, offering a 60% Educational Allowance on the purchase or rent of an IBM 1620 Model I computer that had been launched in October 1959.
IBM followed that up by again offering the University of Iceland a 60% Educational Allowance on the rent or purchase of an IBM 1620 computer and now the University responded positively.
An agreement for the purchase of an IBM 1620 Model II computer, that had been announced in December 1962 and was a significant improvement on Model I, was signed in December 1963 for delivery in December 1964.

 IBM 1401
IBM introduced two variable precision machines at about the same time: The 1401 and the 1620.
The 1620 had a "flag bit" but it was not nearly as elegant, or truly variable, as the 1401's "Word Mark".
The 1620 did not have variable length instructions, and its' handling of character data was sad by comparison to the 1401; but it was designed to be reliable and low cost.

 IBM Archives: 1620 Data Processing System
The IBM 1620 was a general-purpose, stored-program data processing system for small businesses, research and engineering departments of large companies, and schools requiring solutions to complex problems in the areas of engineering, research, and management science.
With the 1711 model 2 and 1712 Multiplexer and Terminal Unit connected to the 1620, the computer not only received data from analog measuring devices, but fed results through the 1711/1712 to control processes by closing contacts which completed circuits to the instrumentation for closed-loop process control.
1620 symbolic language allowed the programmer to refer to instructions and data in the program by name or other meaningful designation without regard to their location in the machine to facilitate relocating sections of programs, incorporating subroutines, and inserting or deleting instructions.

 Educom Review January/February, 1999
In 1959, I was 17 years old and a sophomore at Haverford when the college acquired its first computer, an IBM 1620.
As part of that acquisition, IBM included a six-week course for any member of the college community (remember this was before the "unbundling" decision).
The questions in their simplest terms were: "to what extent is computer-assisted instruction feasible, effective and affordable?" The answers in their simplest terms were that it was clearly feasible and could be quite effective for certain subjects under certain conditions, but it was very expensive.

 IBM 1620 Model I - Wikipedia, the free encyclopedia
The IBM 1620 Model I was the original implementation of the IBM 1620 scientific computer, introduced in 1959.
One industry magazine (Datamation) mentioned that the 1620 was the first IBM computer for which the basic system could be leased for a monthly rate less than its number.
The first 20,000 decimal digits of Core memory were internal to the CPU itself (which reduced the floor space requirements of the basic system).

Before I got acquainted with the IBM 1620 I thought that in the mean time everybody knew that the most essential property of a general purpose information processing machine is that it allows you in principle to process any piece of information in whatever way you like.
The IBM 1620 is not the only machine on the market, where (part of) the addressing information and the corresponding information proper are positionally dependent.
In the IBM 1620, however, the process is always continued to the bitter end of the destination.

 The IBM family of APL systems - APL programming language - Cover Story IBM Systems Journal - Find Articles   (Site not responding. Last check: 2007-09-10)
The developmental history of IBM subfamilies of APL systems is traced in this paper, focusing on the inter-relationships among them and the methods of implementation used by the various groups involved.
In the 25 years since the first viable APL system was introduced outside of IBM, offerings of APL systems spanning most of the significant hardware families have been produced at a rate of more than one per year.
This work went remarkably well, resulting in an integrated system, APL\360,[6] with excellent performance characteristics.[7] The system was operational about three months after work was started, and the three implementers who did the bulk of the programming were later to receive an industry award for their work.

 IBM 7030 Summary
IBM's bid was based on a renegotiation clause for its proposed machine that would be four to five times faster than requested and cost $3.5 million rather than the requested $2.5 million.
When IBM lost the bid on its high-performance decimal (base-10) computer system the company decided to begin a redesign of the project, and the STRETCH project was begun in 1955.
In use for the next ten years, the eight IBM Stretch 7030 supercomputers were IBM's initial attempt at building computers with transistors designed to "stretch" the speed of its current vacuum tube technology.

 The IBM 407 Accounting Machine
As with all IBM punch-card equipment (except the key punch and sorter), a control panel (left) is wired to specify the details of operation: what card columns to read and what to do with them, how to format the report.
In 1955, the 407 was adapted to act as an input/output device for the IBM 650 computer, and would later perform similar roles for other IBM calculators (such as the CPC-II) and computers (7090); reportedly, a 407 even served as the "system clock" for Columbia's 7094.
There was a model E8, that was offered with the IBM 1620 to be used as an offline printer.

(2) The memory on the IBM 1620 was called the "core," a term used in the StarTrek series to this day (and to their day, too).
(3) The IBM 1620 Model 1 that I worked on had (hold your breath) 20,000 (yes, a two followed by four zeros) digital "characters." Each character was sort of like a byte, but you could not get at the individual bits...
(4) Anyway, the IBM 1620 really was digital in its operation, i.e., numbers (including machine addresses!) in core memory were stored one digit per character, with a "flag" over the leftmost digit that marked the end of the number, and a flag over the rightmost digit if the number was negative.
