Description
More specifically, the work began as a development plan for the Model 15, 25, and 35 and involved improvement of the communication control processor (CCP), development of a new file control processor (FCP), introduction of features such as a 64-kilobyte chip memory, addition of a mid-size model (Model 5), and achievement of the processing capacity improvements needed for the successor machines of the DIPS-11 Model 10, 20, and 30. After about 1 year, additional development began on the Model 45 (the high-end model) as a DIPS ultra-high performance machine, so the Series was expanded to 5 models. This resulted in significant expansion of the performance range.
