Although a previous 'open house' was held in 1965, this 6-page VISITOR's GUIDE handout, describing 10 TOUR Stops, with a first-page cover, "A Word about MRC" by E. F. Lindquist, President, must have been published in early 1968, or possibly late in 1967, as the text on page-3, "SCORING AREA" refers to sheet processing in 1966-67, and also refers to the Model 1501 Card scanner, which was not completed until late 1967/early-1968. The TOUR STOPS include the MRC facilities at 321 and 325 East Market Street (two floors) and the 108 N. Linn Street Engineering Department on the main floor and in the basement - the latter where the Engineering Offices were located - in what we called the 'coal bin'. Although brief and concise, this only surviving VISITOR's GUIDE provides a rare glimpse into the 'bowels' of MRC as it existed shortly prior to the acquisition by Westinghouse Learning Corporation
