Scope and Contents

This issue contains another 'Idea for Design' of mine, (page #98), "Feed-back Path Ups Input of Operational Amplifier". The opposing page #99 contains a large ad by INDIANA GENERAL for core-memory stacks for computer storage - both the product and the company are long since relegated to the scrapheap of history! As are my several design articles that appeared in the above issues! The ELECTRONIC DESIGN Magazine is published yet today, albeit with dramatically different contents and advertisements. ED's 50th Anniversary was celebrated with a special 'retrospective issue' in the October 2002 - readily available in electronic form online

The Press-Citizen and the Daily Iowan newspapers ran feature articles about this event. The headline for the Press-Citizen was "Computer Test Score Firm To Hold Open House Here", and the Daily Iowan headline was "Public to View Test Center". Each article was accompanied by a photo. This JVM Accession Item contains a folder on the Media Disc entitled 1965_09_25_Public Tour of MRC, which contains the JPEG Image scans of each photo, and an MS Word file for each article that contains the JVM text transcription as well as the respective photos. Hard-copy printouts of each MS Word file are also included. Similar data-base files were included in the DVD presented to U of I in an earlier JVM Accession

Scope and Contents

This surviving Original Copy bound document gives a detailed breakdown of all the major components comprising this very high-speed OMR/punched-card system developed by MRC and a west coast company, IKM. This 50-page (+) document concludes with a 21-page section entitled, "MRC Production of 1501 Scanner". The project was fraught with difficulties, including major problems in the liaison/coordination between MRC and the West Coast based sub-contractor, Litton Industries and later, IKM in Chatsworth, CA.

These two 'loose stacks' of several hundred unbound pages, give an insight into the major design projects, activities, major issues/conflicts, critical decisions, time-scales, financial budgets, Technical Staffing levels, trip reports, Letters to-and-from Customers, Engineering Status Reports (monthly, quarterly, year-end), and related events that occurred during this twelve year period, shortly preceding, then following WLC's acquisition of MRC in June 1968. The contents of the two rubber-banded stacks overlap in time to some extent

Scope and Contents From the Collection: The Papers of John V. McMillin II primarily chronicle developments at the Measurement Research Center (MRC), which was founded in 1952 by Prof. Everett F. Lindquist of the University of Iowa College of Education. Prof. Lindquist pioneered the design and use of standardized tests in American public schools, beginning in the late 1920's. By 1953, he and his staff developed an optical mark reader (OMR) for scoring students' test answer sheets. The electronic brain, as the OMR was called at the time, was a breakthrough in providing, for the first time, large-scale high-speed test scoring. However, its vacuum-tube technology was becoming obsolete, and by 1959 MRC began work on the design and development of solid-state, or transistorized, circuitry to replace the less stable vacuum tubes. The bulk of the papers document activities at the MRC from 1959 to about 1980 from the perspective of a project engineer, and later engineering manager, who was closely involved with...

Scope and Contents

Including a handwritten page of Lindquist's analysis. I suspect this is the only surviving copy of what I feel should rightly be regarded as a historical document. The success of this machine spawned a lot of jobs in Iowa City, IA!

Through a JVM-paid subscription to an online searchable data-base, I was able to find several references to Dr. E. F. Lindquist, the founder of ITP, MRC, the co-founder of ACT, and the President of MRC when it was acquired by Westinghouse Learning Corporation in June 1968. The JPEG Image files I have downloaded, and the image-CLIPS and 3 MS Word files I have subsequently created are available in the JVM Archival Media Disc on a folder named: [1926_1946_1951_1952_PRESS-CITIZEN_EFL]
