HP-38G

From Wikipedia, the free encyclopedia

The HP-38G is a programmable graphing calculator by Hewlett Packard. It was introduced in 1995 with a suggested retail price of 79.95 USD. HP credits a committee of eight high school, community college, and university teachers with assisting in the design of the calculator.

The HP-38G, unlike most of HP's other calculators, uses infix notation rather than Reverse Polish notation. Given the calculator's intended userbase of high school math and science teachers and students, this is not surprising. The calculator is programmable, supporting small, interactive applications called "aplets" [sic].

The production of the hp38g has been discontinued (since approx 2004).

Its replacement was the HP-39G (for which a 'pirate' CAS aplet came into circulation), hence there is also an HP-39G+ which has no known CAS aplet implementable.

Also, for European and some other authorities an HP-40G has been available, with an 'on-board' CAS facility. Since 2006, the HP-40G is replaced by the HP-40GS, built on the ARM architecture, and offering both USB and RS232 connectivity.
