notes: label: Description
content: Hewlett-Packard launched this handheld graphing calculator a year after its HP-28C and the two devices are quite similar. The HP-28S had a larger memory, operated more rapidly, and had a subdirectory structure for variables. The case, keyboards, and display are as described for 1999.0291.01. Text above the display reads: hp HEWLETT (/) PACKARD. It also reads: 28S. Further text reads: ADVANCED (/) SCIENTIFIC CALCULATOR. Molded plastic on the back reads: [copyright mark] HEWLETT-PACKARD CO. 1986 (/) MADE IN U.S.A. 2801A04666. The first four digits of the serial number indicate that the calculator was made in the first week of 1988.
label: Description
content: Hewlett-Packard introduced the HP-28S at the January 1988, meeting of the American Mathematical Society, held in Atlanta, Georgia. This meeting began the centennial celebrations of the AMS. Members attending the banquet could purchase an HP-28S with their banquet ticket for an extra charge of $60 (the banquet itself cost $30, the calculator alone $235. A December 1988, article gives the price of the calculator as $165 to $239). Professor Andrew Gleason of Harvard University acquired this calculator at that banquet. A sticker on the cover of the calculator reads: AMERICAN MATHEMATICS (/) 100 (/) YEARS (/) 1888-1988.
