IMPS


Integrated Microcomputer Processing System (IMPS) is the data processing software that the U.S. Census Bureau's developed prior to CSPro. Functionality of IMPS, combined with that of the Integrated System for Survey Analysis (ISSA), formed the backbone of CSPro. The IMPS software is archived here but will not run on modern Windows machines without a proper emulator or virtual machine.
