Hi Brad,
I don't have any need for the book but did use the ECAP program on an IBM 1127 system back in the late 60's. The element nodes were entered on punch cards and a printout of results came pretty quickly. It was very good for filter design.
The original program ran from a removable disk pack.
Regards,
Tom

Hello--
As one of the first programs of its kind, IBM's ECAP (Electronic-Circuit Analysis Program) included many of the features found in modern analysis programs
(e.g., TINA) and a user-interface that's painful by today's standards (punched cards, anyone?). If you're curious about ECAPs innards and applications, I have a book for you.
I have one copy of "IBM Electronic Circuit Analysis Program: Techniques and
Applications" by Randall Jensen and Mark Lieberman; published by Prentice-Hall,
Englewood Cliffs, NJ, 1968 first edition hardcover, 402 pp.. EX-LIBRARY copy
in good condition (card pocket, spine label, library markings). Library of
Congress catalog 68-18515.
I'm asking $5.00 which includes USPS media-mail postage and a cuppa coffee
for yours truly.
Questions welcomed, PayPal honored.
