Very cool book find

Now this is maybe a book that's worth $153. Electronic Analog Computers (Second Edition, Hardcover) Subtitle: D-c Analog Computers Granino A. Korn, Ph.D. and Theresa M. Korn, M.S. McGraw-Hill Book Company, 1956 (Original copyright 1952) The lower-case 'c' is actually how its used in the book and the subtitle. Here's the first couple paragraphs from the preface of the book: D-c analog computers are relatively simple electronic devices now commonly in use to solve a variety of problems in applied mathematics and engineering design. The application of such computers to the simulation of modern automatic control systems has been particularly successful; but some acquaintance with d-c analog techniques can benefit almost any engineer or research worker, no matter what his special field may be. A d-c analog representation of a problem does not merely furnish needed numerical data. It often seves as a working model which helps to close the gap between physical intuition and exact analysis. The continuing remarkable progress in the related fields of electronic computers, instruments, and controls has led naturally to the preparation of a new, completely revised edition of _Electronic Analog Computers_. The greater part of the book has been entirely rewritten. We have attempted to carry out our original purposes, namely 1. To acquaint research and development workers with tried methods for the application of d-c analog computers as computing aids and simulators, and with the possibilities and limitations of such equipment; 2. To present a comprehensive body of up-to-date design information on computer components and systems. We believe that such information is of particlar interest to scientists and engineers engaged in the development of instruments and industrial control devices. *** There are also pictures and descriptions in here of computers that I have never even heard of, such as the Curtiss-Wright analog computer (CURTIAC); the Berkeley EASE (Electronic Analog and Simulation Equipment) computer made by the Berkeley Division of Beckman Instruments, Inc.; the Electronic Associates Precision Analog Computing Equipment (PACE); the Goodyear Electronic Differential Analyzer (GEDA) made by Goodyear Aircraft Corporation; and the Reeves Electronic Analog Computer (REAC) made by Reeves Instrument Corporation, New York City. Also: [A picture of a Donner Scientific analog computer] A complete table-top d-c analog computer priced just below $1,000. The unit comprises ten operational amplifiers, power supplies, all necessary controls, and a removable problem board. Multipliers and function generators are available as accessories (Donner Scientific Co.). [A picture of a Heath analog computer] This complete 15-amplifier machine is available as a do-it-yourself kit for less than $1,000. The amplifier tubes are top-mounted to minimize heating of components. The 30 coefficient-setting potentiometers are set by comparison with a built-in precision voltage divider which is also available for gain measurements (Heath Co.). Wow. The book is in excellent shape, save for the damn price written in grease pencil on the inside cover thanks to the stupid thrift store pricer.
