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

An Invention by E. F. Lindquist. This document consists of 4-pages of typewritten text, followed by 6 pages of Lindquist's original sketches, describing this invention. Likely the first draft of the next two items shown below

An Invention by E. F. Lindquist. This may be identical (or nearly so) to the document of Lindquist's that I show as dated 7/29/1971 in an earlier JVM Accession to UI. This one contains 6 pages of text, and six pages of his sketches. NOTE: the 7/29/71 document includes a cover MEMO to Edberg, and an 8/2/65 EFL letter. A second copy of the 7/29/1971 document is included in this U of I Accession for completeness

Lindquist is instructing the law firm to determine the feasibility of obtaining a U. S. Patent on the above invention

A 2-page JVM Transcribed MRC Engineering Report by Chief Engineer Edberg, Folder: 1965_FALL_Edberg MRC Report. It is reported that Lindquist's Mod I, II, and III Scoring Machines have been salvaged and are no more!

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

This 6-page document, including sketches, was prepared by John V. McMillin, and covers early design concepts for reading colored ink on OMR documents, as well as the traditional #2 pencil marks. Case file 14,042

Lindquist 2-page letter related to the 1965_10_22_MRC Colored Ink Detection System, described above

The JVM Archival Media Disc Folder by this name contains a 4-page MS Word document entitled 1966_FALL_D.P.Wahl M1501 Report_ORG.doc, which shows a JPEG-Image of Pete Wahl's 'Fall of 1966' optimistic assessment of the future of the MRC 1501 CARD SCANNER PROGRAM. My brief commentary is included, along with several MRC M1501 Marketing Brochure pages that were prepared during this era. A hard-copy printout is included in this Accession Set

Lindquist correspondence regarding another U. S. Patent application of his, Case File No. 14,850. This document includes a fold-out drawing of the mechanism, Signed by Edberg, Chief Engineer

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. The Archival DVD Folder 1967_08_11_MRC 1501 CARD SCANNER Cost Analysis contains only a JPEG-Image scan of the Report Cover and First Page, identifying the earliest date in the sections as 8/11/67

Two stacks/bundles. John V. McMillin, Mgr. 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

Describes MRC circa 1967-68 - the Company and the Services available, with an introductory of the main facility at 321 East Market Street and a statement of the Development Mission by Dr. E. F. Lindquist, Founder, including his photo. Original Copy. JPEG Image files on JVM media disc

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
