Bell and Newell (1971) report on p. 517: model #built ----- ------ 701 20 704 50 709 20 7090 50 7094-I 130 7094-II 125 7040 120 7044 120 However, Blaauw and Brooks (1997) report on p. 624 that 123 copies of the 704 were built. (They also report that 18 copies of the 701 were built and about 15 copies of the 702, a decimal/character machine, were built. They give no counts on the the 704 or 705 descendants. E.g., the 7080 was a 705 descendant.) Check Bashe, et al., IBM's Early Computers. (B&B cite their number of 704s as coming from Bashe.) To compare, over 1,800 IBM 650 systems were built and over 12,000 IBM 1401 systems were built. Phister, Data Processing Technology and Economics, includes tables of number-in-use for 1955-1974 (Table II.2.10 on p. 333 in the 2nd edition) and lists the 7090 and 7094-I/II. (Also, he lists IBM models 650, 704, 705&705-III, 1401, 1460, 1620, and 707x -- along with other a couple of Univac and Burroughs systems.) -- Mark Smotherman, Computer Science Dept., Clemson University, Clemson, SC http://www.cs.clemson.edu/~mark/homepage.html ###### From: hancock4@bbs.cpcn.com (Lisa or Jeff) Newsgroups: alt.folklore.computers Subject: Re: 709x series-how many built?

IBM is concerned with selling today's computers and modern technology, such as the web. In 1994 I asked them if there'd be any commerative to mark the 30th anniversary of the introduction of S/360. The answer was no, not at all. They do have an archives where stuff can be researched, but I was wondering if any of the veterans here knew off hand. I also wonder if they built more 7090s or 1401s. I think 1401s were more widespread, IIRC, it was about 10,000 built, but I have to double check. ###### Newsgroups: alt.folklore.computers From: eric@fudge.uchicago.edu (Eric Fischer) Subject: Re: 709x series-how many built?

Would anyone know approximately how many > were built? I don't have anything resembling complete sales figures, but the library here has a copy of Martin H. Weik's _Third Survey of Domestic Electronic Digital Computing Systems_. That book lists the installations of various computers as of March 1961, which includes 65 sites with 704s, 27 with 709s, and 38 with 7090s. The 1964 supplement unfortunately drops the list of installations (in 1961 the lists were already getting long enough to be cumbersome) but says that you can buy a minimally configured 7094 II (how is that different from a 7094?) for $3,018,000. eric
