Circa 1966 Digi-Data Corp. Digital Stepping Recorder Computer Drive, Model 1430, Ser. 823, housed in its original 17″ x 11.5″ x 8″ carrying case, with built-in controls and lighted indicators for power and tape tension. This early 'portable'—but quite heavy—magnetic tape recorder for computers was advertised as offering 'new flexibility to designers of digital systems in the preparation of computer compatible tapes,' driven by the high speed asynchronous stepping capability of the recorder. Specifications for this model included a 0 to 300 steps/second stepping rate, IBM compatible spacing and reel size, end of tape sensing by photocell, and 3/4″ inch inter record gap generation as required by most computers of the period. The device retailed for $3,850 in January 1966. In very good to fine condition.
