Whatwould you dowth a Statistics and Number-Crunching Computer

that starts at $XiOo; has 16K Hardwired Basic Languageand 28 Major Peripherals?

The inew Wang System 2200 is a System.It gives you the raw power and the penrph-erals you must have for a wide range ofproblem solviing. For under $7,200 yOu getaI CPU with 16K bytes of BASIC languageinstructions hardwired inlto the electron-ics ... plus a 4K operatinig memory. Youalso get a big 16 lines (of 64 chlaracterseach) CRT display, a console mag tapedrive and your choice of eitlher alpha orBASIC Keyword keyboards.Some Words About Language: The hard-wired MOS ROM language in your Sys-tern 2200 finally ends your dollar trade-offs ... economy systems that are costly toprogram or very expensive systems that arerelatively easy to program. Many, if notmost, of your people already know BASIC.They'll be solving problems the day yoursystem is delivered (and, we can deliver inabout two weeks). Most of your budgetwill go into problem solving; not systemsupport.

Plenty!Try To Out-Grow ItL Main memory isfield expandable in 4K increments (at $1,500per 4K). Up to 32K. You can choose fromthree kinds (and 7 price ranges) of print-ers ... one even has a stepping motor forvery precise 4-quadrant incremental plot-ting. Speaking of plots, we have a new,very large flatbed (31" X 42") for only$7,500 or a smaller one if you plot small.Both print alphanumerics and plot underfull program control. Been appalled latelyby disk prices? Starting at just $4,000, weoffer you our new "floppy" disk in single,double and triple disk configurations (.25,.50 and .75 MB's). For big disk power, youcan have 1, 2 or 5 megabyte fixed/remov-able disk systems. All peripherals, includ-ing punched or mark sense hopper cardreaders, paper tape readers and on- lineBCD or ASCII controllers are easily added-on in the field so your System 2200 willgrow with your needs.

All prices U'.S. List. If you're the enitrepreneur tvpe we ye just announced a newv 7-module Basic Accounting Systemsoftsvare package for the business eind of your business like payroll, invoicing, inventorv, receivables and some reallyfancv management reports.

The Wise Terminal: If you are now or maysoon be getting into terminals, we haveseveral new products that will instantly up-grade your System 2200 for telecommuni-cations with any other System 2200 or amainframe computer. And, you still havea powerful stand-alone system. Anotherapproach, of course, is to justify it as apowerful terminal and get a "free" stand-alone computer. Wise?We Do A Lot For You: System 2200 isbacked by over 250 factory-trained WangService Technicians in 105 U.S. cities.Naturally, we guarantee or warranty every-thing you buy from us. If you want, thereare free programming/operating schoolshere in Tewksbury, Massachusetts, almostevery week. We have a growing programlibrary on a wide range of statistics andmath/science applications. Our user group(with the unlikely name of "SWAP") couldhelp you cut programming costs even fur-ther. We do a lot for you.

(WANG)Even if you call the Wang System 2200 a small system. . . you have to admit it's a big idea.O Please send literaturea Please have your representative phone me:

For two weeks last summer (June 20-July 4, 1973) a significant international scientificmeeting took place in Mexico City. "Science and Man in the Americas" was attended bymore than 5000 scientists, engineers, government officials, representatives of business andindustry, science journalists, students, educators and laymen from scores of countries.They deliberated a wide range of topics central to the future development and well-beingof the Western hemisphere. The meeting, co-sponsored by AAAS and the Consejo Nacionalde Ciencia y Tecnologia of Mexico, was created in the belief that science is of overridingimportance in the world today and that, being universal, it transcends national boundaries.Here now, captured on audiotape, are many of the most compelling sessions, available forlistening, study, and reflection in your home, library, laboratory, automobile. Another serviceof the AAAS. (Simultaneous translations accompany portions of symposia where necessary.)

Skepticism is a stock trade of science. Thus, the promiseof the green revolution is weighed against its actualcosts . . . the potential of geothermal energy is squareda.gainst problems, environmental and political .. con-tident 20th-century conceptions of prehistory are crit-ically examined . . . our understanding of natural phe-nomena- volcanoes, earthquakes, hurricanes is

questioned. This third volume of Speaking of Scieniceoffers a- wide ranging sampling of skepticisms frompopulation policy to views of man's violent behavior.Knowledgeable people take a sharp-eyed look at twelve

different problems involving science and technology.An insight is gained into current attitudes toward somefamiliar problems ... and a few new ones.
