- HP-38G
The HP-38G is a programmable
graphing calculator byHewlett Packard . It was introduced in 1995 with asuggested 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 thanReverse Polish notation . Given the calculator's intended userbase ofhigh school maths and science teachers and students, this is not surprising. The calculator is programmable, supporting small, interactive applications called "aplets" ["sic "] .ee also

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.External links
