Prototype Workshop of the Center for Technology & Innovation (CT&I) in Binghamton, New York successfully resurrected a 1440 system including a CPU and console, a 1311 disk drive, and a 1442 card reader/punch. An example of a more fully configured 1440reported in 1964: {{cite web • five disk drives • two magnetic tape drives • two card reader-punches • one high-speed printer • an optical reader (to transfer specially coded medical data forms to magnetic tape) ==References==
