The IBM 1401 is a variable-wordlength decimal computer that was announced by IBM on October 5, 1959. The first member of the highly successful IBM 1400 series, it was aimed at replacing unit record equipment for processing data stored on punched cards and at providing peripheral services for larger computers. [1]

Introduced in 1959, the IBM 1401 quickly made inroads into the business community. By the mid-1960s, it comprised more than half of the world’s computers. The 1401 family spawned an entire generation of programmers who first learned computing on these machines.

2015年2月19日 · At its introduction in 1959, the 1401 was not the largest computer on the block; for IBM, that would have been the massive 7090 scientific mainframe, introduced a year earlier, followed by the even-larger STRETCH supercomputer in 1961.

The IBM 1401 -- a predecessor to the System 360 -- had all the processing power and memory of today's arcade games, but it ran three shifts a day, seven days a week keeping track of an inventory of 105,000 items supporting requisitions worth $32 million a month.

2015年7月5日 · This IBM 1401 3D Simulator seems complete enough to assist in training new 1401 programmers, 1401 demonstrators (and is a good refresher for old operators). A program such as this can give the "feel" of computer systems no longer functioning or existing.

The 1401, announced on October 5, 1959, is the first member of the IBM 1400 series. It was the first computer to deploy over 10,000 units. [1] The IBM 1410 has a similar design, but with a larger address space. The IBM 1460 is logically, but not physically, identical to a 1401 with all of the options, with 16,000 characters of memory, and twice ...

IBM 1401 Technical Features. The architecture of the IBM 1401 was designed around a simple, elegant and human-friendly approach: decimal arithmetic and variable-length text strings for its instructions and data.

We cover IBM’s development of the 1401’s basic enabling technologies and trace its origins in business account-ing machines. We highlight its key features and characteristics, its mar -ket succession, and even its appear-ance in popular culture.

IBM's second successful commercial computer (the first was the 650). Introduced in 1959 and offered until 1971, the 1401 was an outstanding success.
