IBM 5153

The following is a list of products, some notable, some less so, from the International Business Machines (IBM) Corporation and its predecessor corporations, beginning in the 1890s, and spanning punched card equipment, time clocks, typewriters, computers, and more.

This list is ; it includes, for example, the AN/FSQ-7, which was not a product in the sense of offered for sale, but was a product in the sense of manufactured—produced by the labor of IBM. Several machines manufactured for the Astronomical Computing Bureau at Columbia University are included, as are some machines built only as demonstrations of IBM technology. Missing are RPQs, OEM products (semiconductors, for example), and supplies (punched cards, for example). These products and others are missing simply because no one has added them.

IBM sometimes uses the same number for a system and for the principal component of that system. For example, the IBM 604 Calculating Unit is a component of the IBM 604 Calculating Punch. And different IBM divisions used the same model numbers; for example IBM 01 without context clues could be a reference to a keypunch or to IBM's first electric typewriter.

Number sequence may not correspond to product development sequence. For example, the 402 tabulator was an improved, modernized, 405.

IBM uses two naming structures for its modern hardware products. Products are normally given a three- or four-digit machine type and a model number (can be a mix of letters and numbers). A product may also have a marketing or brand name. For instance, 2107 is the machine type for the IBM System Storage DS8000. While the majority of products are listed here by machine type, there are instances where only a marketing or brand name is used. Care should be taken when searching for a particular product as sometimes the type and model numbers overlap. For instance the IBM storage product known as the Enterprise Storage Server is machine type 2105, and the IBM printing product known as the IBM Infoprint 2105 is machine type 2705, so searching for an IBM 2105 could result in two different products—or the wrong product—being found.
