A product may also have a marketing or brand name. Products are normally given a three- or four-digit machine type and a model number (it can be a mix of letters and numbers). IBM uses two naming structures for its modern hardware products. For example, the 402 tabulator was an improved, modernized, 405. Number sequence may not correspond to product development sequence. 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. For example, the IBM 604 Calculating Unit is a component of the IBM 604 Calculating Punch. IBM sometimes uses the same number for a system and for the principal component of that system. These products and others are missing simply because no one has added them. Missing are many RPQs, OEM products (semiconductors, for example), and supplies (punched cards, for example). Several machines manufactured for the Astronomical Computing Bureau at Columbia University are included, as are some machines built only as demonstrations of IBM technology. This list is eclectic 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.
The following is a partial list of products, services, and subsidiaries of International Business Machines (IBM) Corporation and its predecessor corporations, beginning in the 1890s.
