Goal of this work:
Present an on-line (compact rather than hi resolution), searchable (ASCII character rather than image) version of the 1,131 page document
"A Third Survey of Domestic Electronic Digital Computing Systems"
Report No. 1115, March 1961

by Martin H. Weik,
published by Ballistic Research Laboratories, Aberdeen Proving Ground, Maryland

Notes:

  • *** Not carefully proof read ***
  • Color photo of book.
  • The distribution list - pages 1117 through 1131 are not included in this conversion.
  • If there are more than four pictures of a given machine, such as the IBM 650 RAMAC, further pictures may be excluded from this conversion.
  • The OCR and HTML process are not perfect, Errors must have been inserted. And there were some obvious character transpositions and other "warts" in the original text.
  • The OCR process was erratic in horizontal position, currently some redundant user responses have not had the horizontal position problem manually corrected.
  • Much of the document was in two columns, in font sizes that are difficult to read on commonly available display systems (CRTs etc.). This conversion separated the two adjacent columns and placed them into one vertically separated column. This results in a document much easier to read on the majority of electronic viewing devices.
  • Character substitutions - no HTML equivalents
    • The greek delta (an isosolese triangle) is represented as a "[delta]"
    • Other Greek letters are approximated by italicized English substitutions.
    • The plus over minus in represented as "+-"
  • 391 images were scanned at 300 pixels/inch (near the resolution of the printing process), reduced to about 800x600 pixel Super VGA size, and presented in medium resolution .jpg, yielding quite good approximations with file sizes of usually 50 to 100 kilo bytes. Some non-grey scale images are presented in .gif if they yielded smaller files.

Factors in presenting this book on-line

Interesting points

  • Table of Contents
  • Installation of Raised Floor, almost universal in "Big Iron" installations.
  • Magnetic tape racks
  • The marketing department of Monroe Calculating did not approve this Photo background ;-)
  • Interesting study of printed circuits for the RCA 501:
    Assembly of Miniature Components Photo
    Modular Assembly of Miniature Components Photo
    Automatically Printed Wiring Photo
    Standardized Modules Photo
  • 8,196 words of Electrostatic Storage at RICE UNIVERSITY
