L.C. Vercellotti, Frank G. Willard · 1968
The stored programdigital computer hasbecomea workhorse incontrol anddatalogging situations inagreatdiversity ofindustrial processes. Reliable equipment demonstrating impres- siveon-line performance hasbeencarrying outamultitude ofcon- trol tasksranging fromthepedestrian tothecomplex. Oneofthe principle reasons forthissuccess istobefoundintheunderlying design philosophy whichemphasizes simplicity ofbothsystemand circuit design. Acontrol processor exemplifying this design approach isthePRODAC 50computer. Someinsight intotheparticular ap- propriateness ofthisdesign tocontrol applications ispresented by meansofacharacterization oftwospecific applications andabrief lookatandananalysis ofthedesign itself.
