- June 30 -- Thousands of SDD men and women in Endicott, San Jose, Poughkeepsie and Kingston, play a role in the announcement of the IBM System/370. A major feature of the new system is the IBM 3211 high speed printer, which had been developed by Endicott. In addition to manufacturing the 3211, SMD Endicott is responsible for other peripheral equipment used with the IBM System/370, including the IBM 3215 console printer, the IBM 3216 type cartridge, IBM 2821 Model 6 control unit, and IBM 3210 Model 1 and Model 2 console printers. Circuit Package Manufacturing (CPM) at Endicott and Owego will supply logic and memory cards, boards and cables required for the 370's Monolithic Systems Technology (MST). CPM also developed sophisticated processes and testing techniques to facilitate manufacture of the advanced memory packages in System/370.
September 23 -- The IBM System/370 Model 145 is announced as the first computer to use monolithic circuits for all memory and logic functions. The SDD Laboratory developed the new product and SMD will assemble, test and ship the machine. CD Laboratory people played a key role in developing advanced packaging techniques for the system's monolithic circuitry, and the Circuit Package Manufacturing organization is responsible for the cards and boards of the 145's internal componentry. Site general manager Fredin calls the 145 "one of the most important contributions Endicott has ever made to the company's product line."

- June 23 -- SMD says that it will ship the first IBM System/370 Model 145 from the Endicott plant to its customer in July, more than a month ahead of schedule. The division also publicly describes how the Endicott plant uses a twin IBM System/360 Model 50 installation for real time monitoring of the manufacturing of Monolithic Systems Technology and Solid Logic Technology circuit cards and boards, an IBM 2790 data communication system to improve manufacturing floor control, and a modified IBM System/360 Model 30 to maintain critical "flight time" adjustments on the hammer unit in the IBM 3211 printer, used with the System/370 and most System/360s.
- Late in the summer -- The Systems Manufacturing Division plants in Endicott and Kingston have more work than they can handle. A call goes out for volunteers to man the production lines for about three months. Some 175 Systems Development Division people from Kingston, Poughkeepsie and Endicott respond, and by October are working in a variety of manufacturing assignments.
- November 9 -- A staff engineer at the Endicott laboratory is awarded a patent for a simple technique for making high fidelity replicas of holograms on a large scale and at low cost.
- January 25 -- The Endicott lab publicly describes how engineers who had developed the IBM 3211 printer devised a built-in jet air stream and vacuum cleaner to clear lint from the print mechanism.
- February -- The IBM 2927 programmable tape to printer developed by SDD Endicott is shipped to Aetna Life and Casualty Company in Hartford.
- March 10 -- Two engineers at the lab devise an efficient way of reconstructing holographic images with simple light sources.
- August 21 -- The company announces the IBM 2991 blood cell processor -- a machine to automatically wash the preserving additives from thawed packed red blood cells -- which was developed at IBM's laboratory in Endicott, N.Y., and is manufactured and marketed by the IBM Information Records Division (IRD).
- September 19 -- A new SDD -- with a singularized name: IBM System Development Division -- is created as a new component of the Data Processing Product Group and given worldwide responsibility for systems definition, architecture and systems management of IBM's principal computer product lines and for systems programming; along with worldwide development and U.S. manufacturing responsibility for communications products, terminals and displays. In its new alignment, the System Development Division is responsible for operating IBM facilities in Raleigh, N.C. and Manassas, Va., and the laboratory at Kingston, N.Y. It also has operations at IBM facilities in Poughkeepsie and Endicott; San Jose; and Boulder, Colo.; Gaithersburg, Md.; and Rochester, Minn. SMD's functions are merged into the newly-formed General Products, System Development and System Products Divisions (SPD). SPD is given responsibility for worldwide development and U.S. manufacturing of larger central processor products, including main storage, logic circuitry, channels and cables. SPD operates manufacturing and development facilities in Endicott.
- May -- The company announces the IBM 3890 document processor, which was developed by SDD engineers at Endicott.

- Manufacturing, engineering and support functions occupy approximately three million square feet of space on the site.
The newest addition to the Endicott roster is the IBM 3895 document reader/inscriber, which optically reads handwritten numbers on checks.
- March -- Endicott operates as a product development and testing site for SPD, GPD and SCD; and a manufacturing site for SPD.
