Modification of the AN/TGC-26 Multiple Address Processing Unit to Accept JANAP 128 Format.
Abstract
The Multiple Address Processing Unit (MAPU) of the AN/TGC-26 tape relay center was originally designed to process ACP 127 message format. With the advent of JANAP 128 as a standardized message format a pressing need was felt for a MAPU modification to allow processing of this format. Under the sponsorship of AFCS/DOOT, a partial MAPU was assembled at the Air Force Institute of Technology, and the code recognition logic circuitry was redesigned. Software simulations of the proposed redesign were tested using the Digital Logic Simulator program on the CDC CYBER computer system. A final prototype version of the modified MAPU was successfully tested at Wellesley Air National Guard Station, Massachusetts, using the personnel and equipment of the 253rd CMBTCG. A final schematic diagram and production recommendations are presented herein. (Author)
