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

Letter written by E. F. Lindquist to the MRC Law firm in Washington, D. C. that handled all MRC applications for U. S. Patents, based upon Lindquist's, McMillin's, and other MRC staff members' inventions. The EFL letter included a 3-page technical description, dated 8/3/65. This invention, as described in Lindquist's letter, covers a concept for automatic detection of an OMR sheet side-registration position during scanning, and secondly, correcting/adjusting for any detected side-shift errors. Case File No. 14,173. The original R/D investigation/conceptualizing activity began July 14, 1965 (see the cross-reference shown earlier in this list) by Lindquist and McMillin: refer to my 16-page handwritten document, dated 7-14-65, including drawings and sketches, also attached. The same document contains witness signatures dated 15 July 1965 by George E. Carsner, and Thomas B. Jacob, MRC Engineers, with the notation "Invented by E. F. Lindquist and John V. McMillin"

Scope and Contents During the early 1960s, various publications referred to this era as "The Golden Age of Electronics", as Electronics Technology was in a state of rapid flux and transition from the former decades-old vacuum-tube era to the dawn of 'transistorized' circuitry, printed-circuit transistor modules, early computer-type logic, and similar solid-state products. My role at MRC as Project Engineer in those days was to 'attack' the old way of doing things, and begin to replace vacuum-tube modules of the first several MRC Test Scoring Machines (Dr. E. F. Lindquist's pioneering invention) with greatly improved, less expensive solid-state components and sub-systems. My opportunity to do this task en-mass came about in 1960-61 when Dr. Lindquist committed MRC Engineering resources to design and construct a specialized test-scoring machine for Professor John C. Flanagan's nation-wide Project Talent, requiring the processing of test sheets from 400,000 students. Shortly after this successful...

Scope and Contents At the time, the early 1960's were referred to as the 'golden age' of electronics, as the seminal 1947 invention of the point-contact transistor by John Bardeen, Walter Brattain, and William Shockley at the Bell Telephone Labs soon revolutionized forever the world of electronics design and ensuing products. The early 1960's foresaw the last vestige of vacuum-tube logic and amplifier circuit designs, which were rapidly being replaced by a wider and wider variety of emerging solid-state designs incorporating germanium and silicon transistors. As a young engineer myself, I was 'swept up' in this revolution, and as a project engineer at Measurement Research Center (MRC) in Iowa City, Iowa my task was to 'transistorize' various components in the first high-speed electronic scoring machine invented by Dr. E. F. Lindquist, President and Founder of MRC. My first of several "Ideas for Design" (pages #146 & 147), "Holding Resistor Allows Narrow Pulse Triggering of SCR Circuit", was...

Similar in scope and contents to the above JVM-to-UI Accession, this issue contains my Idea for Design (pages #192 & 193), "Versatile Transistorized Alarm Detects Pulse Dropouts". I was pleased to receive a letter from ED on May 12, 1961 informing me that my idea had been voted the "most valuable of issue" award, and I was awarded a $50 check. The Original Copy of this magazine is also included

Similar in scope and contents to the two previous issues included in the JVM-to-UI Accession materials. This issue announce that an "Iowa Engineer's Idea Pays $50" on page #1. Again, the folder in the included JVM Archival media disc contains a number of JPEG image scans of electronic/logic components being advertised in the early 1960's. The Original Copy of this magazine is also included

Scope and Contents EDN was another popular magazine subscribed to by electronic/logic designers, such as myself, back in the early 1960's. Refer to pages #72 & 73 for my EDN Packaging Idea article, "Hinged Connector Plate Adds Flexibility to Card Files", which includes four photos of the MRC module being described. Original Copy is provided. The so-called 'hinged plate' was a rather trivial design point, but I used this means to get the article published - replete with the photos - to 'show off' a complex MRC design module incorporated into the early 1960 's innovative OMR DOCUTRAN system designed for MRC's important customer, Science Research Associates, Chicago, Illinois. The module, as shown, contains nearly 50 printed-circuit cards, each containing numerous transistors and related components - all of this support circuitry necessary to drive the 960-bit core-memory module shown in the photograph! A single tiny integrated-circuit chip today (or portion thereof!) could readily handle all of the...

Scope and Contents During 1960/61 MRC designed and constructed a large, complex Optical Mark Read Scanner for an important customer, Science Research Associates. We were forced to hire quite a few SUI Electrical Engineering students (Juniors & Seniors), and as their supervisor, I became exasperated with seemed to me to be their 'common sense' approach to Engineering Practices, in spite of their good grades. Accordingly, on Memorial Day, May 30, 1961, I sat down at my dining room table for about two hours, and scribbled out a 'tongue in cheek' article which I entitled, "DESIGNING MARGINAL CIRCUITS", that 'defined' the Ten Rules (in jest) to 'succeed' in such endeavors - rather a parody of the kinds of miscues I was seeing my SUI students perform. I showed the manuscript to Theodore 'Ted' A. Hunter, a prominent local electrical engineer, who among his many accomplishments had established the well-known LION CLUB's Eye Bank, had founded the Student Quarterly Journal as a new publication within the...
