I just came across fairly clean photocopies of a few old IBM manuals. They are: IBM Electronic Statistical Machine Type 101 - Preliminay Manual of Information (1949) 70 pgs. IBM Electronic Statistical Machine Type 101 - Principles of Operation (third rev. 1949, 1953) 90 pgs. IBM Electric Punched Card Accounting Machines - Principles of Operation - Automatic Summary Punches (1946) 25 pgs. IBM 513, 514 Reproducing Punches - General Information Manual (1945, 1958) 30 pgs. If anyone is interested in copies at cost (.03/pg.; $6.50 total) + postage, and is willing to indemnify me on the copyright issue :-), let me know. -W
